\frac{2}{3}J=15-7
Subtract 7 from both sides.
\frac{2}{3}J=8
Subtract 7 from 15 to get 8.
J=8\times \frac{3}{2}
Multiply both sides by \frac{3}{2}, the reciprocal of \frac{2}{3}.
J=\frac{8\times 3}{2}
Express 8\times \frac{3}{2} as a single fraction.
J=\frac{24}{2}
Multiply 8 and 3 to get 24.
J=12
Divide 24 by 2 to get 12.
