The answers are:

x: 0
y: -14

x: 2
y: -8

x: 3
y: -5

Working out:

y= 3(0)-14
y= 0-14
y= -14


-8 = 3x-14
-8 = 3(2)-14
-8 = 6-14
-8 = -8


y= 3(3)-14
y= 9-14
y= -5

I hope this helped~

Answer:

(x, y) = (0, -14), (2, -8), (3, -5)

Explanation:

Put the given values into the equation and solve.

x = 0

y = 3·0 -14 = -14

y = -8

-8 = 3x -14

6 = 3x . . . . . . add 14

2 = x . . . . . . . divide by 3

x = 3

y = 3·3 -14 = -5

__

The ordered pairs in your table are ...

(x, y) = (0, -14), (2, -8), (3, -5)

_____

Comment on the approach

In this problem, you are only asked for one x-value for a given y-value. If there were more, you would solve the equation generically (x = (y+14)/3) and use that to compute the desired values of x.
