Solve (9x-3)+(5x+5)+2(7x-15)=168

$$( 9 x - 3 ) + ( 5 x + 5 ) + 2 ( 7 x - 15 ) = 168$$

Solve for x

$$x=7$$

Steps for Solving Linear Equation

Combine 9x and 5x to get 14x.

$$14x-3+5+2\left(7x-15\right)=168$$

Add -3 and 5 to get 2.

$$14x+2+2\left(7x-15\right)=168$$

Use the distributive property to multiply 2 by 7x-15.

$$14x+2+14x-30=168$$

Combine 14x and 14x to get 28x.

$$28x+2-30=168$$

Subtract 30 from 2 to get -28.

$$28x-28=168$$

Add 28 to both sides.

$$28x=168+28$$

Add 168 and 28 to get 196.

$$28x=196$$

Divide both sides by 28.

$$x=\frac{196}{28}$$

Divide 196 by 28 to get 7.

$$x=7$$
