Answer 1

need help with these problems too! (image ^)

Answer 2

let a be the first number
and b the second
a=5b
that is for one number is 5 times larger than the other
a-b=120, this is the difference between them being 120 (assuming a is the bigger one)
so a=5b, a-b=120
plug the first equation into the second
a-b=120 becomes 5b-b=120 implies 4b=120 implies b=30, which implies a=150
