Answer 4

yes wouldn't i just from then use the substitution method? @Dido525

Answer 5

Remember, each shirt costs $15.

Answer 6

Or elimination which I find easier. You can use substitution if you want.

Answer 7

@geoffb lol this is a different probelm...

Answer 8

So x=50-2y

Answer 9

Substitute that for x in the second one.

Answer 10

I am sure you can figure it out now.

Answer 11

I know. But my point is that it's essentially the exact same problem, so I don't know why you need help again—especially since you didn't show your work or where you're getting stuck.

Answer 12

@geoffb i'm just not sure on how to set up the problem when i set it up then i know how to do the rest & clearly i wouldn't have posted this question if i was understanding what i need to do i thought this website was for helping and not judging

Answer 13

@Dido525 Thank you so so so much for the help I appreciate it :)

Answer 14

Welcome! :) .

Answer 15

Who's judging?

I thought the answer @ChmE gave in the other post was more than helpful, and would adequately prepare you for this one (since it's the exact same question).

Answer 16

@geoffb I'm not great with word problems, obviously this isnt going anywhere thanks anyways but i understand which in the end is why i came here...
