That goes like two separate questions.

Let s = susie's age now and L = Lita's age now.

Person____________4yearsago________now________
Susie_____________s-4______________s=3*(L-4)
Susie______________________________s=L+2
Lita______________L-4_______________L

TWO descriptions were given about Susie's age now. Both of those depend on Lita's age.
s=s
3%28L-4%29=L%2B2
3L-12=L%2B2
2L-14=0
2L=14
highlight%28L=7%29 and so highlight%28s=9%29
