Solve for s 9s-5g=-4u

$9 s - 5 g = - 4 u$

Add $5 g$ to both sides of the equation.

$9 s = - 4 u + 5 g$

Divide each term in $9 s = - 4 u + 5 g$ by $9$ and simplify.

Divide each term in $9 s = - 4 u + 5 g$ by $9$ .

$\frac{9 s}{9} = \frac{- 4 u}{9} + \frac{5 g}{9}$

Simplify the left side.

Cancel the common factor of $9$ .

Cancel the common factor.

$\frac{9 s}{9} = \frac{- 4 u}{9} + \frac{5 g}{9}$

Divide $s$ by $1$ .

$s = \frac{- 4 u}{9} + \frac{5 g}{9}$

Simplify the right side.

Move the negative in front of the fraction.

$s = - \frac{4 u}{9} + \frac{5 g}{9}$
