2-91.

Solve the system of equations below. Homework Help ✎

*y*= −*x −*2

5*x*− 3*y*= 22

Substitute the first equation for *y* in the second equation.

5*x* − 3(−*x* − 2) = 22

5*x* + 3*x* + 6 = 22

8*x* + 6 = 22

8*x* + 6 − 6 = 22 − 6

8*x* = 16

*x* = 2

Now substitute 2 into the first equation for *y* and evaluate for *x*.
