Answer:
P =3Q +21
Step-by-step explanation:
Given: Rahim was asked to make p the subject of this formula
Q = p/3 - 7
He started his answer as follows
3Q = p - 21 hence p =
To Find, Complete Rahim's final answer.
Solution:
Q = p/3 - 7
Multiply both sides by 3
3Q = 3(p/3 - 7)
3Q = 3 × p/3 - 3 × 7
3Q = p - 21
Adding 21 both sides
3Q + 21 = p -21 +21
3Q + 21 = p
interchange sides
p = 3Q + 21
hence p =3Q +21
