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
