Question

mr. Bronski is three times as old as sam if the difference in their age is 22 find the age of each

Answer 1

b = age of Bronski

s = age of Sam

 

b - s = 22

b = 3s

 

substitute 3s for b in equation 1

 

(3s) - s = 22

2s = 22

s = 11

 

substitute 11 for s in equation 1

b - 11 = 22

b = 33

 

check by substituting both values into equation 2

(33) = 3(11)
