p=1

Explanation:

To solve 3(p-2)+7 = 32-4(2p+5)

Begin by distributing the values outside the parenthesis to the terms inside the parenthesis

3p-6+7 = 32-8p-20

Combine like terms on each side of the equation

3p-6+7 = 32-8p-20

3p+1=12-8p

Now combine the variable terms on the same side of the equation by additive inverse

3p+8p+1 = 12 cancel(-8p) cancel(+8p)

11p+1=12

Now combine constant terms on the same side of the equation by additive inverse

11pcancel(+1) cancel(-1)=12-1

11p=11

Now solve for the variable by multiplicative inverse

(cancel(11)p)/cancel(11) =11/11

p=1
