Y = 3x+7

y = - 2x-3

What would be the x and y for that solution

So if we are solving for x and y. First we need to subtract both equations. We take each equation and put in parenthesis and subtract.

y-y = (3x+7) - (-2x-3) =

0 = 3x+7+2x+3

0 = 5x+10

-10 = 5x

-2 = x.

Now we need to solve for y.

Plug it in for the first equation. - 2*3+7 = - 6+7 = 1

Test if we are correct and try in the second equation.

-2*-2-3 = 4-3 = 1

x = - 2

y = 1
