if you wanna know how to solve this

here is how:

Simplifying 2p + 7 = 21 Reorder the terms: 7 + 2p = 21 Solving 7 + 2p = 21 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + - 7 + 2p = 21 + - 7 Combine like terms: 7 + - 7 = 0 0 + 2p = 21 + - 7 2p = 21 + - 7 Combine like terms: 21 + - 7 = 14 2p = 14 Divide each side by '2'. p = 7 Simplifying p = 7
