put this solution on YOUR website!Let x = my age now
x+27 = Mum's age now
x+5= my age in 5 years
Mum's age now - 8 years = Two times my age in 5 years
x+27 - 8 = 2(x+5)
x+19=2x+10
Subtract x from each side:
x+19-x=2x-x+10
19=x+10
Subtract 10 from each side:
9=x
My age is 9 years NOW, and Mum's age is 9+27=36 years NOW.
Check:
Eight years ago Mum was 28. My age in 5 years will be 14. Indeed, her age eight years ago was twice my age in 5 years.
