two years ago a woman was 7 times old as her daughter, but in 3 years time she would be 4 times old as the girl. how old are they now
d = daughter's age now
w = woman's age now two years ago w-2 = 7(d-2) re-arrange to w = 7d -12
w+3 = 4(d+3) sub in the red equation
7d-12 +3 = 4d+12
3d = 21
d = 7 then mom = 37 *** edited *** Thanx , Guest for noticing my error.....I should have checked my answer !!
