-2x-4=12x+9
Combine 15x and -3x to get 12x.
-2x-4-12x=9
Subtract 12x from both sides.
-14x-4=9
Combine -2x and -12x to get -14x.
-14x=9+4
Add 4 to both sides.
-14x=13
Add 9 and 4 to get 13.
x=\frac{13}{-14}
Divide both sides by -14.
x=-\frac{13}{14}
Fraction \frac{13}{-14} can be rewritten as -\frac{13}{14} by extracting the negative sign.
