If (4,y) is a solution to x-2y = 6, what is the value of y?

(4, -1)

Step-by-step explanation:

(4, y) is a solution to x - 2y = 6.

Find the value of y:

The value of y is '-1'.

(4, -1) is a solution to the equation.

Hope this helps.

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
