Solve 10(0.15)+3(0.38)+25(0.29)+15x=21.89

$$10 ( 0.15 ) + 3 ( 0.38 ) + 25 ( 0.29 ) + 15 x = 21.89$$

Solve for x

$$x=0.8$$

Steps for Solving Linear Equation

Multiply 10 and 0.15 to get 1.5.

$$1.5+3\times 0.38+25\times 0.29+15x=21.89$$

Multiply 3 and 0.38 to get 1.14.

$$1.5+1.14+25\times 0.29+15x=21.89$$

Add 1.5 and 1.14 to get 2.64.

$$2.64+25\times 0.29+15x=21.89$$

Multiply 25 and 0.29 to get 7.25.

$$2.64+7.25+15x=21.89$$

Add 2.64 and 7.25 to get 9.89.

$$9.89+15x=21.89$$

Subtract 9.89 from both sides.

$$15x=21.89-9.89$$

Subtract 9.89 from 21.89 to get 12.

$$15x=12$$

Divide both sides by 15.

$$x=\frac{12}{15}$$

Reduce the fraction \frac{12}{15} to lowest terms by extracting and canceling out 3.

$$x=\frac{4}{5}$$
