A club puts its members into 5 groups for an activity. After 7 students have to leave early,
there are only 3 students left to finish the activity. How many students were in each group

I think that there were 12 students in each group fam.

Step-by-step explanation:

i believe it is 12

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
