Solve 3x+5^circ+2x+45^circ+9x-10^circ=180

$$3x+5 ^ { \circ } +2x+45 ^ { \circ } +9x-10 ^ { \circ } =180$$

Solve for x

$$x=10$$

Steps for Solving Linear Equation

Combine 3x and 2x to get 5x.

$$5x+5+45+9x-10=180$$

Add 5 and 45 to get 50.

$$5x+50+9x-10=180$$

Combine 5x and 9x to get 14x.

$$14x+50-10=180$$

Subtract 10 from 50 to get 40.

$$14x+40=180$$

Subtract 40 from both sides.

$$14x=180-40$$

Subtract 40 from 180 to get 140.

$$14x=140$$

Divide both sides by 14.

$$x=\frac{140}{14}$$

Divide 140 by 14 to get 10.

$$x=10$$
