8\times \frac{3}{4}=3x
Multiply both sides of the equation by 48, the least common multiple of 6,16.
\frac{8\times 3}{4}=3x
Express 8\times \frac{3}{4} as a single fraction.
\frac{24}{4}=3x
Multiply 8 and 3 to get 24.
6=3x
Divide 24 by 4 to get 6.
3x=6
Swap sides so that all variable terms are on the left hand side.
x=\frac{6}{3}
Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
