5x+12=2x-2x-4
Combine 7x and -2x to get 5x.
5x+12=-4
Combine 2x and -2x to get 0.
5x=-4-12
Subtract 12 from both sides.
5x=-16
Subtract 12 from -4 to get -16.
x=\frac{-16}{5}
Divide both sides by 5.
x=-\frac{16}{5}
Fraction \frac{-16}{5} can be rewritten as -\frac{16}{5} by extracting the negative sign.
