Question

Is p=-2 as solution to the following equation?

-15 = 3(2p - 1)

Answer 1

Yes, p = -2 IS a solution.

Explanation:

To check if a number is a solution, you substitute the -2 in place of the p in the equation. Use order of operations to simplify and see if you get -15.

-15 = 3(2p - 1)

-15 = 3 (2*-2 - 1)

-15 = 3(-4 - 1)

-15 = 3(-5)

-15 = -15 Yes!

Answer 2

yes

Explanation:

• 
  `-15=3(2*-2-1`
• 
  `-15=3(-4-1)`
• 
  `-15 = 3(-5)`
• 
  `-15=-15`

Therefore, the answer is yes.
