Answer:

[tex] x = \frac{11}{2} \\ [/tex]

Step-by-step explanation:

f(x) = 2x - 7

when x = 4

It means that equate f(x) to the value of x that's 4 and solve for x

That's

f(x) = 4

We have

[tex]2x - 7 = 4[/tex]

Add 7 to both sides of the equation

[tex]2x + 7 - 7 = 4 + 7 \\ 2x = 11[/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{11}{2} \\ [/tex]

We have the final answer as

[tex]x = \frac{11}{2} \\ [/tex]

Hope this helps you
