Question

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

5p = 4

15p = 10

9 = 4

12 = 13

Answer 1

Move all the p's to one side and the number to the other side: 9p + p - 2p - 3p = 7 - 3 5p = 4

Answer 2

Option (a) is correct.

5p = 4

Explanation:

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

We have to simplify the given equation 9p + 3 = − p + 7 + 2p + 3p.

Consider the given equation 9p + 3 = − p + 7 + 2p + 3p

Like terms are terms having same variable with same power.

Adding like terms, we get,

9p + 3 = 7 + 4p

Subtract 4p both isde, we have,

9p - 4p + 3 = 7 + 4p -4p

Simplify, we get,

5p + 3 = 7

Subtratc 3 both isde, we have,

5p = 4

Thus, option (a) is correct.
