i bought 3 large sandwiches for a picnic. 9 people come to the picnic. how can i cut the sandwiches 3 different ways so each person gets an equal share?

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

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

- (2, -7)

- lines r and s and lines t and u must be parallel
