Whats is 2+2?
im confused pls explain

2 + 2 = 4

Step-by-step explanation:

He answer is simple just like if there is 1 candy and another candy we say that there r 2 candies

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

nope.   happens to me as well.
