w = -0.5

Explanation:

8w-8-6w=4w-7

Collect like terms on the left-hand side:

2w-8=4w-7

Subtract 2w off both sides in order to 'transfer' the operation:

2w-8-2w=4w-7-2w

-8=4w-7-2w

-8=2w-7

From here, 'transfer' the -7 to the left-hand side by doing the opposite operation:

-8+7=2w-7+7

-1=2w

Divide -1 by 2 to get: -0.5

So, w=-0.5

To check, substitute -0.5 into the equation:

8(-0.5)-8-6(-0.5)=-9

4(-0.5)-7=-9

Ta-da! Hope this helps!
