2\times 4\times \frac{4}{5+6}=x\times 5\times 7
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of x,2.
8\times \frac{4}{5+6}=x\times 5\times 7
Multiply 2 and 4 to get 8.
8\times \frac{4}{11}=x\times 5\times 7
Add 5 and 6 to get 11.
\frac{8\times 4}{11}=x\times 5\times 7
Express 8\times \frac{4}{11} as a single fraction.
\frac{32}{11}=x\times 5\times 7
Multiply 8 and 4 to get 32.
\frac{32}{11}=x\times 35
Multiply 5 and 7 to get 35.
x\times 35=\frac{32}{11}
Swap sides so that all variable terms are on the left hand side.
x=\frac{\frac{32}{11}}{35}
Divide both sides by 35.
x=\frac{32}{11\times 35}
Express \frac{\frac{32}{11}}{35} as a single fraction.
x=\frac{32}{385}
Multiply 11 and 35 to get 385.
