4x - 3x = -9 + 30 2 (2x - 17) + 4 = -3 (3 + x)
So, we are going to DISTRIBUTE
Lets work on the left side of the equation first
Multiply 2 on the out side of the parenthesis by what is on the inside
2 x 2x = 4x
2 x -17 = -34
So on the left side we now have
4x - 34 + 4
add 4
4x - 30
Let's do the same thing on the other side
-3 x 3 = -9
-3 x X = 3x
Now let's put everything together
4x - 30 = -9 + 3x
COMBINE LIKE TERMS
x = 21
