Answer:
23/14
Step-by-step explanation:
42x - 5 = 64
Add 5 to both sides in order to isolate 42x
42x = 64 + 5
42x = 69
Divide 42 from both sides in order to isolate x
x = 69/42
The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.
Hey!

Try it yourself, I'll explain the concept
In a function, each x-value matches to exactly one y-value
If it matches to more than one y-value, it is not considered a function
Now look at the x and y values in each table to determine if it is a function or not
