5x=8\times 15+12-3^{2}
Divide 8 by \frac{1}{15} by multiplying 8 by the reciprocal of \frac{1}{15}.
5x=120+12-3^{2}
Multiply 8 and 15 to get 120.
5x=132-3^{2}
Add 120 and 12 to get 132.
5x=132-9
Calculate 3 to the power of 2 and get 9.
5x=123
Subtract 9 from 132 to get 123.
x=\frac{123}{5}
Divide both sides by 5.
