9x-\left(14+2x\right)=-42
Multiply both sides of the equation by 3.
9x-14-2x=-42
To find the opposite of 14+2x, find the opposite of each term.
7x-14=-42
Combine 9x and -2x to get 7x.
7x=-42+14
Add 14 to both sides.
7x=-28
Add -42 and 14 to get -28.
x=\frac{-28}{7}
Divide both sides by 7.
x=-4
Divide -28 by 7 to get -4.
