Two years ago a man was six times as old as his daughter. in 18 years he will be twice as old as his daughter. determine their present ages.

Step-by-step explanation:

f- 2 = 6(d-2)

f - 2 = 6d - 12

f = 6d - 12 + 2

f = 6d - 10       eq 1

f + 18 = 2(d+18)

f + 18 = 2d + 36

f= 2d + 36 - 18

f = d + 18       eq 2

eq1=eq2

6d - 10 = 2d + 18

6d - 2d = 18 + 10

4d = 28

d = 28/4

d = 7 yrs is the daughter's age

Take eq 1

f = 6(7) - 10

f = 42 - 10

f = 32 yrs is Father's age
