Solve for x x+3+x-8+x=55

$x + 3 + x - 8 + x = 55$

Step 1

Simplify $x + 3 + x - 8 + x$ .

Add $x$ and $x$ .

$2 x + 3 - 8 + x = 55$

Add $2 x$ and $x$ .

$3 x + 3 - 8 = 55$

Subtract $8$ from $3$ .

$3 x - 5 = 55$

Step 2

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

Add $5$ to both sides of the equation.

$3 x = 55 + 5$

Add $55$ and $5$ .

$3 x = 60$

Step 3

Divide each term in $3 x = 60$ by $3$ and simplify.

Divide each term in $3 x = 60$ by $3$ .

$\frac{3 x}{3} = \frac{60}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{60}{3}$

Divide $x$ by $1$ .

$x = \frac{60}{3}$

Simplify the right side.

Divide $60$ by $3$ .

$x = 20$
