Answer:
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,
