The solution for 4p+8p=78

p = 13/2

Step-by-step explanation:

Solve for p:

4 p + 8 p = 78

Hint: | Add like terms in 4 p + 8 p.

4 p + 8 p = 12 p:

12 p = 78

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 12 p = 78 by 12:

(12 p)/12 = 78/12

Hint: | Any nonzero number divided by itself is one.

12/12 = 1:

p = 78/12

Hint: | Reduce 78/12 to lowest terms. Start by finding the GCD of 78 and 12.

The gcd of 78 and 12 is 6, so 78/12 = (6×13)/(6×2) = 6/6×13/2 = 13/2:

p = 13/2
