4(x + 3) = 6-x what is the answer I need help please

Amanda [17]

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'.
$\frac{6}{-5} =x$
Seventh, change the whole fraction into a negative.
$-\frac{6}{5} =x$
Eighth, switch your sides.
$x = -\frac{6}{5}$

Answer as fraction: $-\frac{6}{5}$
Answer as decimal: -1.2
