To find the value of x when f(x) = 1, we start with the function f(x) = 2x + 7.
We are given that f(x) = 1, so we set the equation:
2x + 7 = 1
Next, we need to isolate x. We can do this by first subtracting 7 from both sides of the equation:
2x + 7 – 7 = 1 – 7
This simplifies to:
2x = -6
Now, we divide both sides by 2 to solve for x:
x = -3
Thus, the value of x is -3.
