Verified Answer :

4p + 3(p + 4) = 12p + 12
4p + 3p + 12 = 12p + 12
7p + 12 = 12p + 12
5p = 0
p = 0

Answer:

Option (3) is correct.

p = 0

Step-by-step explanation:

Given : equation \(4p\:+3\left(p+\:4\right)\:=\:12p+\:12\)

We have to simplify for p and choose the correct option from the given options.

Consider the given equation \(4p\:+3\left(p+\:4\right)\:=\:12p+\:12\)

Expand brackets by multiplying 3 with each term of bracket, we have,

\(3(p+4)=3p+12\)

Thus, given equation becomes,

\(4p+3p+12=12p+12\)

Add similar terms, 4p and 3p, we have,

\(7p+12=12p+12\)

Subtract 12 from both sides, we have,

\(7p+12-12=12p+12-12\)

Simplify, we have,

\(7p=12p\)

Subtract 12p both sides, we have,

\(7p-12p=12p-12p\)

Simplify,

-5p = 0

This implies p = 0

Thus, option (3) is correct.
