7-107.

Find the point of intersection of the system of linear equations below. Homework Help ✎

8 − 3x = y

2y + 3x = 5

Rearrange the top equation so that it matches the form of the bottom equation.
y − 3x = −8
2y + 3x = 5

Solve the system of equations by eliminating the x's.
y = −3

Now substitute the value for y back into one of the original equations to solve for x.
