You can put this solution on YOUR website!
let m = her ages now
:
write an equation for what it says:
:
"Eight years ago, Melanie was half the age she will be in 3 years."
m - 8 = .5(m + 3)
m - 8 = .5m + 1.5
m - .5m = 1.5 + 8
.5m = 9.5
m = 9.5%2F.5
m = 19 yrs
:
:
Check that in the given statement;
19 - 8 = .5(19+3)
11 = .5(22)
