- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 5
f(3) is x = 3
<u>Step 2: Solve</u>
- Substitute: f(3) = 2(3) + 5
- Multiply: f(3) = 6 + 5
- Add: f(3) = 11
Answer:
Step-by-step explanation:
If you need to substitute the equation x = y - 1.
If you have another equation, then you would plug in y - 1 into the x value of the equation you would need to substitute into.
