Answer:
x = 3 and y = - 1
Step-by-step explanation:
1a. 2x + y = 5 Solve for y in the first equation.
y = -2x + 5
1b. 2(-2x + 5) = 2x - 8
-4x + 10 = 2x - 8
-6x + 10 = -8
-6x = -18
1c. x = 3
2y = 2x - 8
2y = 2(3) - 8
2y = 6 - 8
2y = -2
y = -1
Check Use x = 3; y = -1
1d. 2x + y = 5 2y = 2x - 8
2(3) - 1 = 5 2(-1) = 2(3) - 8
6 - 1 = 5 -2 = 6 - 8
5 = 5 -2 = -2 Checked
