Question

Please help me with this equation -1/2(12p-42)=-33

Answer 1

$-\frac{1}{2}(12p-42)=-33$

Multiplying by (-2) at both sides of the equation:

$\begin{gathered} (-2)\cdot(-\frac{1}{2})(12p-42)=(-2)\cdot(-33) \\ 12p-42=66 \end{gathered}$

Adding 42 at both sides of the equation:

$\begin{gathered} 12p-42+42=66+42 \\ 12p=108 \end{gathered}$

Dividing by 12 at both sides of the equation:

$\begin{gathered} \frac{12p}{12}=\frac{108}{12} \\ p=9 \end{gathered}$
