# Evaluate: 9-4(2p-1)=41

## Expression: $9-4\left( 2p-1 \right)=41$

Distribute $-4$ through the parentheses

$9-8p+4=41$

$13-8p=41$

Move the constant to the right-hand side and change its sign

$-8p=41-13$

Subtract the numbers

$-8p=28$

Divide both sides of the equation by $-8$

\begin{align*}&p=-\frac{ 7 }{ 2 } \\&\begin{array} { l }p=-3 \frac{ 1 }{ 2 },& p=-3.5\end{array}\end{align*}
