7-73.

Find the point of intersection of the lines 3 = 6*x − y* and 3*x* − 2*y* = 24. Homework Help ✎

One strategy to solve this problem is to solve it as a system of equations.

3*x* − 2*y* = 24

6*x* − *y* = 3

Multiply the bottom equation by −2 to cancel out the *y*'s.

3*x* − 2*y* = 24

−12*x* + 2*y* = −6

−9*x* = 18

Solve for *x*, then substitute the value back into one of the original equations to solve for *y*.
