Question 1086867
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
