Solve for c -1/4c-5=20

$- \frac{1}{4} c - 5 = 20$

Combine $c$ and $\frac{1}{4}$ .

$- \frac{c}{4} - 5 = 20$

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

Add $5$ to both sides of the equation.

$- \frac{c}{4} = 20 + 5$

Add $20$ and $5$ .

$- \frac{c}{4} = 25$

Multiply both sides of the equation by $- 4$ .

$- 4 (- \frac{c}{4}) = - 4 \cdot 25$

Simplify both sides of the equation.

Simplify the left side.

Simplify $- 4 (- \frac{c}{4})$ .

Cancel the common factor of $4$ .

Move the leading negative in $- \frac{c}{4}$ into the numerator.

$- 4 \frac{- c}{4} = - 4 \cdot 25$

Factor $4$ out of $- 4$ .

$4 (- 1) \frac{- c}{4} = - 4 \cdot 25$

Cancel the common factor.

$4 \cdot - 1 \frac{- c}{4} = - 4 \cdot 25$

Rewrite the expression.

$- - c = - 4 \cdot 25$

Multiply.

Multiply $- 1$ by $- 1$ .

$1 c = - 4 \cdot 25$

Multiply $c$ by $1$ .

$c = - 4 \cdot 25$

Simplify the right side.

Multiply $- 4$ by $25$ .

$c = - 100$
