If function gis defined by the equation y-3x = -14, which equation represents the function in function notation? O A g(x) = 3x - 14
OB. 8(X) = -3x - 14
OC 8(*) = 3x + 14
OD. 8(X) = -3x + 14

B

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
