Solve the system by substitution.

9y = x

- 4x + y = - 35

Answer: The answer is 7x.

The answer is x=9 and y=1

Step-by-step explanation:

First, you have to substitute x from - 4x to 9y which is - 4 (9y).

That would equal - 36y.

Then the second equation would look like this:

-36y + y = - 35

Then simplify. If you add - 36y and y, it would equal - 35y.

-35y = - 35

Divide - 35 on each side.

y = 1

To find the x value, you have to plug 1 into the first equation. (It doesn't matter which equation you plug into).

So if you plug it into the first equation it would look like this:

9 (1) = x

9 = x
