5x+4-15x=7
Subtract 15x from both sides.
-10x+4=7
Combine 5x and -15x to get -10x.
-10x=7-4
Subtract 4 from both sides.
-10x=3
Subtract 4 from 7 to get 3.
x=\frac{3}{-10}
Divide both sides by -10.
x=-\frac{3}{10}
Fraction \frac{3}{-10} can be rewritten as -\frac{3}{10} by extracting the negative sign.
