Question

I want help with this equation -1 + x = 8x - 8

Answer 1

Answer:

x=1

Step-by-step explanation:

To solve for x, we need to get x alone on one side of the equation.

Add one to each side of the equation.  Subtract 8x from each side of the equation.  Divide both sides by -7.  You should get 1 as the answer.

$-1+x=8x-8\\x=8x-7\\-7x=-7\\x=1$

Answer 2

Answer:

x = 1

Step-by-step explanation:

First combine like terms from both sides, in this case moving the -8 to the left side and the x to the right side.

You do this by doing the opposite operation for the values.

Add 8 to both sides and cancel out -8.

-1 + x = 8x -8

+8             +8

Subtract x from both sides and cancel out x.

7 + x = 8x

   -x     -x

Then it looks like this.

7 = 7x

Divide by 7 on both sides

x = 1
