Question

x + y = −3
y = 2x + 2
how do I solve this equation?

Answer 1

Well, this is a simple system of equations equation. Our first step is to find one value by subtracting the other one.

x + y = -3
-2x + y = 2

We can multiply the top side by 2 so we can subtract the x value and solve for the y value.

2x + 2y = -6
-2x + y = 2

Solve it through by combing the top and bottom.

3y = -4
y = -4/3

We then take -4/3 and substitute it for y in the first or second equation. I'll give you the equation so you can solve for yourself:

x + -4/3 = -3

Answer 2

alr thx

Answer 3

Of course <3

Answer 4

Or you could have just substituted the second equation into the first haha

but same stuff
