16x+2=-2x-15
Subtract 3 from 5 to get 2.
16x+2+2x=-15
Add 2x to both sides.
18x+2=-15
Combine 16x and 2x to get 18x.
18x=-15-2
Subtract 2 from both sides.
18x=-17
Subtract 2 from -15 to get -17.
x=\frac{-17}{18}
Divide both sides by 18.
x=-\frac{17}{18}
Fraction \frac{-17}{18} can be rewritten as -\frac{17}{18} by extracting the negative sign.
