O x=4

Answer 1

`g(x)=f(2)` for x = 4

Explanation:

If
`f(x)=3x-1`

and
`g(x)= 2x-3`

Then for which value of "x" does
`g(x)=f(2)` ?

So start by evaluating what
`f(2)` is:

`f(x)=3x-1\,\,\,\,therefore\,\,\,\, f92)=3\,(2)-1=6-1=5`

Then,we have to find for which value of x
`g(x)=5`

so we write g(x) explicitly:

`2x-3=5\\2x=5+3\\2 x = 8\\x = 8/2\\x=4`
