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
Answer:
Step-by-step explanation:
-7+ 2x = -6x -71
Cancel out the equation to add on to the other side. Anyway works.
If you add or subtract a number from left to right, the other add or subtract needs to be right to left. Vise versa.
-7 +2x = -6x -71
+7 +6x = +6x +7
-7 +2x = -6x -71
+7 +6x = +6x +7
Then you will get: -8x = -64
Because X is not by itself, you want to divide the number by itself cancel out ONLY the number and not X. When you cancel out a number, it has to be applied to the whole equation and thus you will get -64/-8 = Answer
8x = -64
8 = 8
X = -8
