Answer:

(x, y) = (2, 3)

Explanation:

You want the solution to the system of equations.y=-2x+7, y=5x-7.

Solution

Equating the expressions for y gives ...

-2x +7 = 5x -7

14 = 7x . . . . . . . add 7+2x

2 = x . . . . . . . . . divide by 7

y = 5(2) -7 = 3 . . find y from the second equation

The solution is (x, y) = (2, 3).
