Question 1143852
t = tracey's age.
s= sipho's age.
t = 5 * s
t + s = 18
replace t with 5 * s to get 5 * s + s =18
combine like terms to get 6 * s = 18
solve for s to get s = 18 / 6 = 3
that makes t = 5 * 3 = 15
t = 15 years of age.
s = 3 years of age.
t = 5 * s becomes 18 = 5 * 3 which becomes 18 = 18 which is true.
t + s = 18 becomes 15 + 3 = 18 which becomes 18 = 18 which is true.
solution is confirmed to be good.
solution is tracey is 15 years old and sipho is 3 years old.
