7-60.

Solve each system. Homework Help ✎

*y*+ 3*x*= −10

5*x*−*y*= 26

*x*= 7 − 2*y*+

4x*y*= 4

The second equation can be rewritten as −*y* + 5*x* = 2 (Commutative Property of Addition).

(−1, −7)

Which equation should you change into *y = mx + b* form so that you can substitute it into the other equation?
