From 3x-2y=5, we get the formula that represents y by x, y=(5-3x 2).
It is known that the binary equation 3x+4y=10, when x=0, y=(5 2, when.
x = (10 3), y = 0 (note: 10 3 refers to 10/3, the above title is -2/5-3x).
In the equation 2x-3y=1, y, expressed by an algebraic expression containing x, y=(1-2x3).
If m-n=5, then 15-m+n=(
When x = 1/2, the two numbers in the solution of the binary system of equations for the letters x,y: ax+2y=5 and 2x-by=5 are opposite to each other, then a=(
12),b=(8
A and B solve the system of equations ax+by=2 and mx-7y=8 at the same time, A solves it correctly, and gets x=3, y=-2, and B writes m incorrectly to get x=-2, y=2, then in the original equation a=(

In fact, it is to make the coefficient of x become 1, 3x-2y=5 has more -2y on the left, so move - do +, you get 3x=5+2y, and the coefficient before x has an extra 3, so divide by 3 on both sides, you get x=5 3+2y 3,

x (3y) =y (2x-5y) x=3y or 2x=-y and y unequal scattered ridge at 0 , 2x is not equal to calendar 5y The first case: when 2x=-y -4x+12y-8=-(y-6)+28 when the maximum is reached, y=6 so x=-3 so 22x-33y= -264 The second case: when x=3y, -4x+12y-8=-36(y-1 6)-7 reaches the maximum permeability, y=1 6 x=1 2 22x-33y= Please forgive me for the fact that I am too sleepy and may miscalculate.

3x-2y=5, move the term to obtain: -2y=5-3x, and solve: y=3x-5 2
So the answer is: 3x-5 2

2(3y-3)=5x-4
6y-6=5x-4
6y=5x-4+6
6y=5x+2
y=(5x+2)/6
If you don't understand, you can ask.
If it helps, remember to slip and roll pure, ready to sell thank you.
I wish you progress in your studies!

6y-6=5x-4
Detain: Town type dress 6y=5x+2
Both sides except for the imperial stove in 6
Get: y=5 6x+1 3
Remember, thank you if it helps.
I wish the study of rent trillions of progress !!

Subtract 2x from both sides of the equation at the same time to get 3y=5-2x
Then divide both sides of the equation by 3 at the same time

Solution: y=20 >>>More
First, define the domain.
2x 5 is greater than or equal to 0, and x is greater than or equal to 0, and the solution is x greater than or equal to 5 2 so x is greater than 0 >>>More
