Solve for x 240-3x=75

$240 - 3 x = 75$

Step 1

Move all terms not containing $x$ to the right side of the equation.

Subtract $240$ from both sides of the equation.

$- 3 x = 75 - 240$

Subtract $240$ from $75$ .

$- 3 x = - 165$

Step 2

Divide each term in $- 3 x = - 165$ by $- 3$ and simplify.

Divide each term in $- 3 x = - 165$ by $- 3$ .

$\frac{- 3 x}{- 3} = \frac{- 165}{- 3}$

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

$\frac{- 3 x}{- 3} = \frac{- 165}{- 3}$

Divide $x$ by $1$ .

$x = \frac{- 165}{- 3}$

Simplify the right side.

Divide $- 165$ by $- 3$ .

$x = 55$
