Question

How to solve for x and y using elimination method? -4y-11x=36; 20=-10x-10y

Answer 1

Im so confused on how to line the equations up

Answer 2

Rearrange the terms so that it has the x term first, then the y term and the constant term to the right.
-4y-11x=36 can be rewritten as:
-11x - 4y = 36
Multiply each term by -1
11x + 4y = -36 -------- (1)

The next equation is: 20=-10x-10y which can be rewritten as:
-10x - 10y = 20
This equation could be further simplified by dividing each term by -10:
x + y = -2 -------- (2)

Now can you solve for x and y?
