Solve 0.6(10000)+0.8x=0.72(10000+x)

$$0.6(10000)+0.8x=0.72(10000+x)$$

Solve for x

$$x=15000$$

Steps for Solving Linear Equation

Multiply 0.6 and 10000 to get 6000.

$$6000+0.8x=0.72\left(10000+x\right)$$

Use the distributive property to multiply 0.72 by 10000+x.

$$6000+0.8x=7200+0.72x$$

Subtract 0.72x from both sides.

$$6000+0.8x-0.72x=7200$$

Combine 0.8x and -0.72x to get 0.08x.

$$6000+0.08x=7200$$

Subtract 6000 from both sides.

$$0.08x=7200-6000$$

Subtract 6000 from 7200 to get 1200.

$$0.08x=1200$$

Divide both sides by 0.08.

$$x=\frac{1200}{0.08}$$

Expand \frac{1200}{0.08} by multiplying both numerator and the denominator by 100.

$$x=\frac{120000}{8}$$

Divide 120000 by 8 to get 15000.

$$x=15000$$
