The school ordered cases of sports drinks for the 4th grade field day. They ordered 36 cases and each case contained 24 drinks. If each student received three drinks. How many students were there in the 4th grade?

288 kids dude

Step-by-step explanation:

thats a lot of drinks

if x decreases by 4 then y increases by 10

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
