Question

Which of these is a simplified form of the equation 7p + 4 = − p + 9 + 2p + 3p?

A 13p = 13

B 3p = 5

C 7 = 4
D 11 = 15

Answer 1

i think the answer is B 3p = 5

Answer 2

Option (b) is correct.

3p = 5

Explanation:

Given : equation 7p + 4 = − p + 9 + 2p + 3p

We have to write the simplest form of the equation 7p + 4 = − p + 9 + 2p + 3p and choose the correct from the given options.

Consider the given equation

7p + 4 = − p + 9 + 2p + 3p

Simplify , for p on right side by adding similar terms, we get,

7p + 4 = 9 + 4p

Now subtract 4p both side, we have,

7p - 4p + 4 = 9 + 4p - 4p

Simplify , we have,

3p + 4 = 9

Subtract 4 both side, we have,

3p + 4 - 4 = 9 - 4

Simplify, we have,

3p = 5

Thus, Option (b) is correct.
