x=27

Explanation:

Let's ignore the #-8# for now. Distribute the #4# across the #x -3)#

#4(x-3)= 4x-12#

Now we'll work with the #-8#.

Our new equation is #-8+4x-12=3x+7#.

We have some like terms to combine, so let's do that!

#-8+(-12)= -20#

#4x-20=3x+7#

Add #20# to both sides

#4x=3x+27#

Subtract 3x from both sides to get x=27
