\frac{5+x}{-3}=\frac{10}{3}
Divide both sides by 3.
5+x=\frac{10}{3}\left(-3\right)
Multiply both sides by -3.
5+x=\frac{10\left(-3\right)}{3}
Express \frac{10}{3}\left(-3\right) as a single fraction.
5+x=\frac{-30}{3}
Multiply 10 and -3 to get -30.
5+x=-10
Divide -30 by 3 to get -10.
x=-10-5
Subtract 5 from both sides.
x=-15
Subtract 5 from -10 to get -15.
