a.total of their ages is 67.the age of b is

Answer 1

Define x:

Let A be x years old

B is( x - 5 )  years old

C is ( x - 3 ) years old

Form equation and solve x:

Their total age is 67

x + ( x - 5) + (x - 3) = 67

x + x - 5 + x - 3 = 67

3x - 8 = 67

3x = 75

x = 25

Find the age if B:

B = x - 5 = 25 - 5 = 20 years old

Answer:  B = 20 years old
