In 8 years, a girl will be 3 years older than twice her present age.
How old is she now?
:
let a = the girls present age
:
Write an equation for the statement:
:
"In 8 years, a girl will be 3 years older than twice her present age.
a + 8 = 2a + 3
8 - 3 = 2a - a
5 = a
The girl is 5 yrs old now
;
:
Check it in the statement:
"In 8 years, a girl will be 3 years older than twice her present age."
5 + 8 = 2(5) + 3
