Solve for s 8-7s+7=9s-1

$8 - 7 s + 7 = 9 s - 1$

Step 1

Add $8$ and $7$ .

$- 7 s + 15 = 9 s - 1$

Step 2

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

Subtract $9 s$ from both sides of the equation.

$- 7 s + 15 - 9 s = - 1$

Subtract $9 s$ from $- 7 s$ .

$- 16 s + 15 = - 1$

Step 3

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

Subtract $15$ from both sides of the equation.

$- 16 s = - 1 - 15$

Subtract $15$ from $- 1$ .

$- 16 s = - 16$

Step 4

Divide each term in $- 16 s = - 16$ by $- 16$ and simplify.

Divide each term in $- 16 s = - 16$ by $- 16$ .

$\frac{- 16 s}{- 16} = \frac{- 16}{- 16}$

Simplify the left side.

Cancel the common factor of $- 16$ .

Cancel the common factor.

$\frac{- 16 s}{- 16} = \frac{- 16}{- 16}$

Divide $s$ by $1$ .

$s = \frac{- 16}{- 16}$

Simplify the right side.

Divide $- 16$ by $- 16$ .

$s = 1$
