Question

How do you do 7x+7=2x+2

Answer 1

Answer:

x=-1

Step-by-step explanation:

To solve this you need to isolate x to one side. You must add/subtract/multiply/divide both sides.

First, subtract 2x from both sides so x is only on the left side.

7x+7=2x+2

-2x       -2x

5x+7=2

Next, subtract 7 from both sides to isolate x.

5x+7=2

-7     -7

5x=-5

Last, divide both sides by 5 to solve for x.

5x/5=-5/5

x=-1
