Equations are expressions separated by an "equal to" sign

Given the equation 5c + cd. We are to evaluate it if c = 1/5 and d = 15

Substitute the value of c and d into the given expression:

f(c, d) = 5c + cd

f(1/5, 15) = 5(1/5) + 1/5(15)

f(1/5, 15) = 1 + 15/5

f(1/5, 15)  = 1+ 3

f(1/5, 15)  = 4

Hence the value of 5c + cd if c = 1/5 and d = 15 is 4
