How do you solve for x if f(x) = 2x + 7 and f(x) = 1?

To find the value of x, we need to set the two expressions for f(x) equal to each other based on the information provided:

Given the functions:

  • f(x) = 2x + 7
  • f(x) = 1

We start by equating the two:

2x + 7 = 1

Now, let’s solve for x:

  1. Subtract 7 from both sides:
    2. 2x + 7 - 7 = 1 - 7
    2x = -6
  2. Now, divide both sides by 2:
    3. x = -6 / 2
    x = -3

So, the solution is:

x = -3

In conclusion, if f(x) = 2x + 7 and f(x) = 1, then the value of x is -3.
