p − 15 = 13 − 6 p
− 15 − 13 = − 6 p − p
− 28 = − 7 p
− 7 − 28 = − 7 − 7 p
4 = p
4 − 15 = 13 − 6 ( 4 )
− 11 = − 11
P-15=13-6p +6p +6p
7p-15=13 +15 +15
7p = 28 7 7 p = 4
To solve the equation P − 15 = 13 − 6 p , first combine like terms and isolate P . The solution is P = 4 , and verifying it shows that both sides of the equation are equal. Therefore, the solution is confirmed.
