Devan Cox · Answer 1

So 5a=cost of adults

3s=cost of students

a+s=1142

5a+3s=4326

a+s=1142

subtract s from both sdies

a=1142-s

subsitute 1142-s for a

5 (1142-s) + 3s=4326

5710-5s+3s=4326

5710-2s=4326

subtract 5710 from both swides

-2s=4326-5710

-2s=-1384

dividee both sides by 2

-s=-692

multiply - 1

s=692

692 students

subsittue

a+692=1142

subtract 692

a=450

s=692

a=450
