when andy was born, sarah, his mother was 25 years old. three years ago his mother was six times as old as andy was then. how old is andy now. show method you used to solve the problem.
***
let x=Andy's age now
x+25=mother's age now (mother will always be 25 yrs older than Andy)
3 years ago:
x-3=Andy's age
x+25-3=x+22=mother's age
At this time, his mother was six times as old as andy
x+22=6(x-3)
x+22=6x-18
5x=40
x=8
x+25=33
Andy's age now=8
mother's age now=33
