(5.02) solve the system of equations.

-7x - 2y = -13
x - 2y = 11

part a: use the substitution method to solve the system. show each step of the process to receive full credit. write the solution as an ordered pair.

part b: use the elimination method to solve the system. show each step of the process to receive full credit. write the solution as an ordered pair.

x=3, y=-4. (3, -4).

Step-by-step explanation:

-7x-2y=-13

x-2y=11

x=2y+11

-7(2y+11)-2y=-13

-14y-77-2y=-13

-16y=-13+77

-16y=64

y=64/-16

y=-4

x-2(-4)=11

x+8=11

x=11-8

x=3
