Solve for s 8-4s=s+13

$8 - 4 s = s + 13$

Step 1

Move all terms containing $s$ to the left side of the equation.

Subtract $s$ from both sides of the equation.

$8 - 4 s - s = 13$

Subtract $s$ from $- 4 s$ .

$8 - 5 s = 13$

Step 2

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

Subtract $8$ from both sides of the equation.

$- 5 s = 13 - 8$

Subtract $8$ from $13$ .

$- 5 s = 5$

Step 3

Divide each term in $- 5 s = 5$ by $- 5$ and simplify.

Divide each term in $- 5 s = 5$ by $- 5$ .

$\frac{- 5 s}{- 5} = \frac{5}{- 5}$

Simplify the left side.

Cancel the common factor of $- 5$ .

Cancel the common factor.

$\frac{- 5 s}{- 5} = \frac{5}{- 5}$

Divide $s$ by $1$ .

$s = \frac{5}{- 5}$

Simplify the right side.

Divide $5$ by $- 5$ .

$s = - 1$
