Solve for s s+s+8+12=38

$s + s + 8 + 12 = 38$

Step 1

Simplify $s + s + 8 + 12$ .

Add $s$ and $s$ .

$2 s + 8 + 12 = 38$

Add $8$ and $12$ .

$2 s + 20 = 38$

Step 2

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

Subtract $20$ from both sides of the equation.

$2 s = 38 - 20$

Subtract $20$ from $38$ .

$2 s = 18$

Step 3

Divide each term in $2 s = 18$ by $2$ and simplify.

Divide each term in $2 s = 18$ by $2$ .

$\frac{2 s}{2} = \frac{18}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 s}{2} = \frac{18}{2}$

Divide $s$ by $1$ .

$s = \frac{18}{2}$

Simplify the right side.

Divide $18$ by $2$ .

$s = 9$
