Solve 54=xleft(1-0.3right)(1-0.05)

$$54 = x \left( 1-0.3 \right) (1-0.05)$$

Solve for x

$$x = \frac{10800}{133} = 81\frac{27}{133} \approx 81.203007519$$

Steps for Solving Linear Equation

Subtract 0.3 from 1 to get 0.7.

$$54=x\times 0.7\left(1-0.05\right)$$

Subtract 0.05 from 1 to get 0.95.

$$54=x\times 0.7\times 0.95$$

Multiply 0.7 and 0.95 to get 0.665.

$$54=x\times 0.665$$

Swap sides so that all variable terms are on the left hand side.

$$x\times 0.665=54$$

Divide both sides by 0.665.

$$x=\frac{54}{0.665}$$

Expand \frac{54}{0.665} by multiplying both numerator and the denominator by 1000.

$$x=\frac{54000}{665}$$

Reduce the fraction \frac{54000}{665} to lowest terms by extracting and canceling out 5.

$$x=\frac{10800}{133}$$
