F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4

Answer:
x = 27/5
Step-by-step explanation:
Step 1: Write equation
-12 = -5(x - 3)
Step 2: Solve for <em>x</em>
- Distribute -5: -12 = -5x + 15
- Subtract 15 on both sides: -27 = -5x
- Divide both sides by -5: x = 27/5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-12 = -5(27/5 - 3)
-12 = -5(12/5)
-12 = -12
