Step-by-step explanation:
Hi,
We're dealing with linear functions. 
We have here the first function.

That's a linear function, with slope, and no linear coefficient since
But on the other hand, the functions below, they all describe parallel lines, since their slope has the same value. I've changed the letters to make it easier the comprehension.
Even though each one has the same slope value, they have different non zero linear coefficients, {-6,-18,6,18}. Unlike, the first one

A possible solution would be adjusting any of these, whose operation would result in g(x)=3x, but

Answer:

Step-by-step explanation:
We want to find

This can be rewritten as;


Recall that; 

We evaluate now to obtain;

25-4x=16-4x
25-4x+4x=16-4x+4x
25=16
No solution
