How to solve a system of binary equations such as 60X 30Y 1080 50X 10Y 840 Please explain

60x+30y=1080 ①

50x+10y=840 ②

Multiply by 1 to get: 60x+30y=1080 Multiply by 3 to get: 150x+30y=2520 by - get:

x=16 substitute x=16 into , and get:

y=4So, the solution of the original system of equations is x=16 y=4

Simplification 6x+3y=108

5x+y=84

Re-2x+y=36

5x+y=84

The lower ones are minus the upper ones.

3x=48x=16

Bring in. 2*16+y=36y=4

The first part, the elimination of the element. It is to change the duality into the unity.

Multiply the second equation by 3 and subtract the first equation.

90x=1440

You can calculate x, and then you can find y by bringing in an equation at random

The original equation is simplified to 6x+3y=108

5x+y=84

Re-2x+y=36

5x+y=84②

By the way.

3x=48x=16

Bring x=16 in.

2*16+y=36

y=4 The solution of the original equation is.

x=16y=4

Simplify: 2x+y=36 ; 5x+y=84 subtract the first equation from the second formula:

3x=48 brings in the first formula: y=4

60x+30y=1080①

50x+20y=880②

10x+10y=200

Substituting 50x+20y=30x+2 (10x+10y)=30x+400=880

Solve x and substitute any formula to solve y, both of which are fractions, and solve them yourself.

30x+30y=400 by laughing 8 to slip this 240x+240y=320080y-80x=400 multiplied by 3 to get 240y-240x=1200240x+240y=3200)-(240y-240x=1200) to get the letter to rise to 480y=200

The rest is your own.

60x+30y=180 Be careful.

50x+10y=840 ②

Will grind 3- got.

90x=2340

x=26 and x=26 are substituted for .

50*26+10y=840

1300+10y=840

10y=-460

y=-46, i.e., the solution of the original equation is x=26, y=-46

1) 60x+30y=1080 (30 on both sides at the same time) to get (3) (2) 50x+10y=840 (10 on both sides at the same time) to send filial piety (dust scatter 4) (3) 2x+y=36 (Shen 4) 5x+y=84 (subtract from (3) 3x=48x=16 to (3) y=36-2*16=36-32=4 to check (1)60*16+30*4=960+120=1080(2)50*16+10....

Subtracting the two equations gives y=400, and then brings back to the first equation to get: x=300

Don't forget to give a good review.
