x=27

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

How do you solve -8+ 4( x - 3) = 3x + 7-8+ 4( x - 3) = 3x + 7?
