let's try a system with three variables and three equations!

solve the system of equations:

2x+3y+2z=13

2y+z=1

z=3

question 12 options:

(5,-1,3)

(3,5,-1)

(1,2,3)

(0,-5,3)

c: lkllmn.

hope it's you

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
