1400 8600 100y 800y 2400 200x find x and y

Summary. 800x+1000y=53000,800x-400y=6000 to find the value of x,y.

Hello dear, I will answer for you immediately, you wait a moment [than the heart] [than the heart] [than the heart] [than the heart] I will write the process on paper, take a picture and send it to you.

Okay. Look at the kiss.

The specific steps are on **.

This is a binary equation.

1000y-400y=1400y？

1000y-(-400y)=1400y

Summary. Solution: Scale the equation as a whole. Then, according to the law of elimination, the values of x and y are found respectively.

How to calculate 40000x=8000+4000y+1200y=3600+200x. Good. Hurry up.

There is one more question. This question.

Okay. Hello, is the first question you just said a system of equations?

Hello, did you post this question for the first question?

Solution: Scale the equation as a whole. Then, according to the law of elimination, the values of x and y are found respectively.

Summary. 49500+100y=17000x27000+200x=9000y can be converted into 495+y=170x270+2x=90y498 90=44820170 90=1530044802+90y=15300x44802+270=45072=168xx=45072 168=268y=170 26-495=45114

Help calculate 49500+100y=17000x, 27000+200x=9000y, find x and y

49500 + 100y = 17000x27000 + 200x = 9000y can be slowed down into the Zhensen core 495 + y = 170x270 + 2x = 90y498 90 = 44820170 90 = 1530044802 + 90y = 15300x44802 + 270 = 45072 = 168xx = 45072 168 = 268y = 170 26-495 = 45114

So x=268y=45114 okay

Use the previous one directly, and then use this to subtract 300x+200y=49000, and 200y minus 200y. 400x-300x = 100x, while 60000 minus 49000 and so on are 11000. So 100x=11,000.

The book is marked with x=110. Bring in any of the original equations. Like what.

200 110 + 100 y is equal to 30,000. Alas, 22000+100y=30000, Sochen argues that 100y=8000, so, y=80, so x=110, y=80

200x+100y=30000①

300x+200y=49000 Socks Mountain.

Potato good base 2- number of deceit.

400x+200y-300x-200y=60000-49000100x=11000

x = 110 substitution to get 22000 + 100y = 30000100y = 8000

y=80

1800+50y=11000x

1500+1000x=350y

180+5y=1100x ①

150+100x=35y

7, got. 1260 + 35y = 7700x + get. 7600x=1410

x=141 760, this formula Hongchang substitution, Qing Sui.

y=183/38

The solution of the system of equations is ,x=141/760y=183/38

Summary. Dear, the process of solving this problem is as follows: x+y=10008x+4y=6400 deformation, 8x+8y=80008y-4y=8000-64004y=1600y=400

x+y=1000-||8x+4y=6400

Teach me how to substitute x and eliminate x.

Dear, the process of solving the problem is as follows: x+y=10008x+4y=6400 deformation, 8x+8y=80008y-4y=8000-64004y=1600y=400

Substituting the elimination x method: x=1000x=1000-y, substituting 8 (1000 y) + 4y=64008000-8y+4y=64004y=1600y=400

What is the method of eliminating x?

Kissing, called addition, subtraction and elimination.

Teach that. Ways to eliminate x.

The steps to solve the binary one-square radical group by the addition, subtraction, and elimination method are as follows 1.Using the basic properties of the equation, the coefficients of an unknown number in the original system of equations are reduced to equal or opposite numbers

2.Then use the basic properties of the equation to add or subtract the two deformed equations, remove an unknown number, and obtain a unary equation (be sure to multiply both sides of the equation by the same number, do not multiply only one side, and then use subtraction if the unknown coefficient is equal, and add if the unknown coefficient is the opposite of each other);3.

Solve this unary one-time square Mingchen merger and find the value of the unknown;

I'm not going to do it first.

The process of solving this question is as follows: x+y=10008x+4y=6400 deformation: 8x+8y=80008y-4y=8000-64004y=1600y=400x=1000-400=600

What is the method?

The method is to add and subtract the elements.

Summary. Simplify 200x+300y=300000 to: 2x+3y=3000

200x+300y=300000, find x and y hello! We're happy to answer for you! What is the other formula? Please send us the full question so that it can help you better.

Simplify 200x+300y=300000 to: 2x+3y=3000 Another formula is similar to Suiqing: 4x+5y=5000 and 2x+3y=3000 to 4x+6 y=6000, and then, y=1000, x=0

x and y cannot be 0

Is that just a formula?

x =750，y =500
