4(x + 3) = 6 - x

First, expand to remove parentheses.

4x + 12 = 6 - x
Second, subtract '6' from both sides.

4x + 12 - 6 = -x
Third, subtract '12 - 6' to get 6.

4x + 6 = -x
Fourth, subtract '4x' from both sides.

6 = -x - 4x
Fifth, since 'x' can be referred to as '1', add it to '4x' to get '-5x'.

6 = -5x
Sixth, divide both sides by '-5'.

(6)/(-5) =x
Seventh, change the whole fraction into a negative.

-(6)/(5) =x
Eighth, switch your sides.

x = -(6)/(5)

Answer as fraction:
-(6)/(5)
Answer as decimal: -1.2
