Answer 1

let's let p = # of pants and s = # of shirts

if 1 pair of pants is $20, then p pairs costs 20*p
repeat this same logic with the shirts
add them together and set them equal to the total cost ($100)

^ that'll get you your first equation

to get your second equation: he wants to buy 6 items, so shirts and pants have to add up to 6. write the equation to match this idea.

once you have both equations, write them together to get your system

Answer 2

so p =2 s = 4

Answer 3

well the part you showed me is just asking for an equation, but if you went ahead and solved it, that's correct

Answer 4
