Solve x+(x+21.6)+(x+13.2)=150

$$x+(x+21.6)+(x+13.2)=150$$

Solve for x

$$x=38.4$$

Steps for Solving Linear Equation

Combine x and x to get 2x.

$$2x+21.6+x+13.2=150$$

Combine 2x and x to get 3x.

$$3x+21.6+13.2=150$$

Add 21.6 and 13.2 to get 34.8.

$$3x+34.8=150$$

Subtract 34.8 from both sides.

$$3x=150-34.8$$

Subtract 34.8 from 150 to get 115.2.

$$3x=115.2$$

Divide both sides by 3.

$$x=\frac{115.2}{3}$$

Expand \frac{115.2}{3} by multiplying both numerator and the denominator by 10.

$$x=\frac{1152}{30}$$

Reduce the fraction \frac{1152}{30} to lowest terms by extracting and canceling out 6.

$$x=\frac{192}{5}$$
