Solve (18000).05x+.04x=(18000-x).04

$$(18000).05x+.04x=(18000-x).04$$

Solve for x

$$x=\frac{9000}{11251}\approx 0.799928895$$

Steps for Solving Linear Equation

Multiply 18000 and 0.05 to get 900.

$$900x+0.04x=\left(18000-x\right)\times 0.04$$

Combine 900x and 0.04x to get 900.04x.

$$900.04x=\left(18000-x\right)\times 0.04$$

Use the distributive property to multiply 18000-x by 0.04.

$$900.04x=720-0.04x$$

Add 0.04x to both sides.

$$900.04x+0.04x=720$$

Combine 900.04x and 0.04x to get 900.08x.

$$900.08x=720$$

Divide both sides by 900.08.

$$x=\frac{720}{900.08}$$

Expand \frac{720}{900.08} by multiplying both numerator and the denominator by 100.

$$x=\frac{72000}{90008}$$

Reduce the fraction \frac{72000}{90008} to lowest terms by extracting and canceling out 8.

$$x=\frac{9000}{11251}$$
