3x+4=15x+125
Multiply both sides of the equation by 5.
3x+4-15x=125
Subtract 15x from both sides.
-12x+4=125
Combine 3x and -15x to get -12x.
-12x=125-4
Subtract 4 from both sides.
-12x=121
Subtract 4 from 125 to get 121.
x=\frac{121}{-12}
Divide both sides by -12.
x=-\frac{121}{12}
Fraction \frac{121}{-12} can be rewritten as -\frac{121}{12} by extracting the negative sign.
