Question

-5 (p+2)=2 (2p-15)+p

Answer 1

$-5 (p+2)=2 (2p-15)+p$ 

$-5p-10=4p-30+p$  $\text{Expand}$ 

$-5p-10=5p-30$ 

$-10=5p-30+5p$  $\text{Add 5p to both sides}$ 

$-10=10p-30$ 

$-10+30=10p$  $\text{Add 30 to both sides}$ 

$20=10p$ 

$\dfrac{20}{10}=p$  $\text{Divide both sides by 10}$ 

$p=2$  $\text{Solution}$
