You can put this solution on YOUR website! let j = James age
let e = Emily's age
:
Write an equation for each statement
:
James is 47 years old.
j = 47
He is three time older than Emily minus 4 years.
j = 3e - 4
replace j with 47 (from the first statement)
47 = 3e - 4
add 4 to both sides
47 + 4 = 3e
51 = 3e
divide both sides by 3
e = 51/3
e = 17
How old is Emily.
Emily is 17

;
Check this in the 2nd statement
47 = 3(17) - 4

James is 47 years old.
He (is 47, which is) three time older than Emily minus 4 years.
47 = 3E - 4
Can your granddaughter finish from there?

Let Emily's age be E
James, being three times OLDER than Emily, minus 4 years, would be FOUR (4) TIMES as old as Emily, minus 4, or 4E - 4
James, being three times AS OLD as Emily, minus 4 years, would be THREE (3) times as old as Emily, minus 4, or 3E - 4
I believe you meant the latter!
Is this how it was really worded?
