I don't get this one.

I don't' get this. :( It doesn't make sense to me all at.
let a = larger and b = smaller
if you know how to use substitution, you should be able to go from there if not, let me know and i'll explain the rest

okay, give me a second.
i don't get it. :(
okay, well first, do you understand what I did there?
not really. Sorry
the difference between larger and smaller is 29 means larger - smaller =29
now for larger just make it a; so a=larger, b=smaller, from now on we use a and b
so a (larger) - b (smaller) =29
okay. I get that part.
the sum means adding so: 5b+2a=156
okay. Got it.
so again your two equations are
so, move b to the right side in equation 1 getting:
then plug the value (29+b) for a in to the second equation.
you should then be able to solve for b, once you get b plug the value for b into either equation to get a.
a and b will be your two numbers
oh okay. i think i can take it from here. Thanks so much!!
no problem , just following those steps exactly should take you straight to the answer:) as long as they make sense to you
