Question

Solve 20) -11 + 10(p + 10) = 4 - 5(2p+11)

Answer 1

Given the equation :

$-11+10(p+10)=4-5(2p+11)$

Solve for p :

$\begin{gathered} -11+10p+10\cdot10=4-5\cdot2p-5\cdot11 \\ -11+10p+100=4-10p-55 \end{gathered}$

Combine the like terms :

$\begin{gathered} 10p+10p=4-55+11-100 \\ 20p=-140 \\ \\ p=-\frac{140}{20}=-7 \end{gathered}$

So, the answer is : p = -7
