15x+12=4x-5
Combine 3x and x to get 4x.
15x+12-4x=-5
Subtract 4x from both sides.
11x+12=-5
Combine 15x and -4x to get 11x.
11x=-5-12
Subtract 12 from both sides.
11x=-17
Subtract 12 from -5 to get -17.
x=\frac{-17}{11}
Divide both sides by 11.
x=-\frac{17}{11}
Fraction \frac{-17}{11} can be rewritten as -\frac{17}{11} by extracting the negative sign.
