Find the value of x. (1 point) a.40 b.50 c.80 d.60

I want to tell you it is A bit I have no idea if I did that correctly so I won’t show my work and you’re best to ask google for how to solve questions like that, as opposed to asking us folk.

y/x=18

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
