Q. Given f(x)=2x−5 f(x)=2 x-5 , solve for x x when f(x)=7 f(x)=7 .\newlineAnswer:
  1. Given function: We are given the function f(x)=2x−5f(x) = 2x - 5 and we need to find the value of xx when f(x)=7f(x) = 7. We can set up the equation 2x−5=72x - 5 = 7 to solve for xx.
  2. Addition to isolate x: Add 55 to both sides of the equation to isolate the term with xx on one side.\newline2x−5+5=7+52x - 5 + 5 = 7 + 5\newline2x=122x = 12
  3. Division to solve xx: Divide both sides of the equation by 22 to solve for xx.2x2=122\frac{2x}{2} = \frac{12}{2}x=6x = 6
