aldin, joel, marcus and lyle want to share 1/2 of a large pizza equally. how much much will each boy eat?

they will get 1/3 each of the half or how much is remaining cut into 3

Step-by-step explanation:

because 1.2 isnt half of 6 duh

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
