Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 7
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute: f(-3) = 2(-3) + 7
- Multiply: f(-3) = -6 + 7
- Add: f(-3) = 1
5x + 4 = 7x
Subtract 4 from both sides.
5x = 7x - 4
Subtract 7x from both sides.
5x - 7x = -4
Simplify.
-2x = -4
Divide both sides by -2.
x = 4/2
x = 2
