Answer:
x = -8
Step-by-step explanation:
to solve this kind of problem is very simple , just be very careful about the negative and positive signs.
-7+2x = -6x -71
we will collect the like terms or simply say that you will combine the like terms
we have,
-7 + 2x + 6x = -71
2x + 6x = -71 + 7
8x = -64
divide both sides by 8
8x/8 = -64/8
x = -8
