Ello there,

The following question is asking for us to determine the x value if the y value is 5.

In order for us to solve this we start by plugging in 5 for the y value:

5 = 3x - 7

Now we add 7 to both sides:

12 = 3x

Then we divide both sides by 3:

4 = x

Therefore, when the output is 5 the input has to be 4.

Hope I helped,
