Answer:
y=1
Step-by-step explanation:
5y(2x-1)=y(x+2)+20, x=3
5y(2(3)-1)=y(3+2)+20
5y(6-1)=y(5)+20
5y(5)=5y+20
25y=5y+20
25y-5y=20
20y=20
y=20/20
y=1
To find out all of the possible combinations, just multiply the amount of each variable:
4*2*5 = 40
There are 40 different combinations consisting of a sandwich, soup, and drink.
