Answer:
This equation is invalid, therefore there is no solution.
Step-by-step explanation:
2x + 8 = 2(x + 4)
8 + 2x = 2(x + 4)
8 + 2x = 2(4 + x)
8 + 2x = (4 * 2 + x * 2)
8 + 2x = (8 + 2x)
8 + 2x + -2x = 8 + 2x + -2x
8 + 0 = 8 + 2x + -2x
8 = 8 + 2x + -2x
8 = 8 + 0
8 = 8
This equation is invalid, therefore there is no solution.
