\frac{315\times 3}{8}+x=150
Express \frac{315}{8}\times 3 as a single fraction.
\frac{945}{8}+x=150
Multiply 315 and 3 to get 945.
x=150-\frac{945}{8}
Subtract \frac{945}{8} from both sides.
x=\frac{1200}{8}-\frac{945}{8}
Convert 150 to fraction \frac{1200}{8}.
x=\frac{1200-945}{8}
Since \frac{1200}{8} and \frac{945}{8} have the same denominator, subtract them by subtracting their numerators.
x=\frac{255}{8}
Subtract 945 from 1200 to get 255.
