5168=\frac{\left(280-x\right)\times 0.8\times 34}{0.75}
Divide 280-x by \frac{0.75}{0.8\times 34} by multiplying 280-x by the reciprocal of \frac{0.75}{0.8\times 34}.
5168=\frac{\left(280-x\right)\times 27.2}{0.75}
Multiply 0.8 and 34 to get 27.2.
5168=\left(280-x\right)\times \frac{544}{15}
Divide \left(280-x\right)\times 27.2 by 0.75 to get \left(280-x\right)\times \frac{544}{15}.
5168=\frac{30464}{3}-\frac{544}{15}x
Use the distributive property to multiply 280-x by \frac{544}{15}.
\frac{30464}{3}-\frac{544}{15}x=5168
Swap sides so that all variable terms are on the left hand side.
-\frac{544}{15}x=5168-\frac{30464}{3}
Subtract \frac{30464}{3} from both sides.
-\frac{544}{15}x=-\frac{14960}{3}
Subtract \frac{30464}{3} from 5168 to get -\frac{14960}{3}.
x=\frac{-\frac{14960}{3}}{-\frac{544}{15}}
Divide both sides by -\frac{544}{15}.
