let a = Jean's age now
:
Write an equation for exactly what it says
:
one half of jeans age two years from now plus one third of her age three years ago is twenty years.
(a + 2) + (a - 3) = 20
get rid of the fractions, multiply by 6
6*(a + 2) + 6*(a - 3) = 6(20)
Cancel out the denominators
3(a+2) + 2(a-3) = 120
distribute
3a + 6 + 2a - 6 = 120
5a = 120
a = 120/5
a = 24 yrs is Jean's present age
:
;
check that in the given statement
"(24 + 2) + (24 - 3) = 20"
(26) + (21) = 20
13 + 7 = 20
