Which expression would be easier to simplify if you used the commutative property to change the order of the numbers?

O A. Ķ +(-3) +5

O B. 20+17+(-) + (-)

O C. (-17) + 45+ (-33)

D. 20 + 80 + (-32)

answer: the equation matches the regression

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

it is c, trust i got your back lol
