-16+15-3x=5x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
-1-3x=5x
Add -16 and 15 to get -1.
-1-3x-5x=0
Subtract 5x from both sides.
-1-8x=0
Combine -3x and -5x to get -8x.
-8x=1
Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{-8}
Divide both sides by -8.
x=-\frac{1}{8}
Fraction \frac{1}{-8} can be rewritten as -\frac{1}{8} by extracting the negative sign.
