One-third of Ellen's age last year plus double her age next year is 11 years.
How old is Ellen?
:
let e = her present age
:
write an equation just like it says.
1%2F3(e-1) + 2(e+1) = 11
Get rid of the fraction mult by 3, resulting in:
e - 1 + 6(e+1) = 33
e - 1 + 6e + 6 = 33
e + 6e + 5 = 33
7e = 33 - 5
7e = 28
e = 28/7
e = 4 yrs old is Ellen
:
YOu can confirm this, replace e with 4 in the original equation
