Because I said so
Answer:
6
Step-by-step explanation:
Note: f(x) = y
f(x) = 2x + 2 x = 2
Step 1: Plug in 2 into x.
f(x) = 2(2) + 2
Step 2: Then multiply 2 times 2.
f(x) = 4 + 2
Step 3: Add.
f(x) = 6

Answer:
Infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Alg I</u>
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
x = y - 3
2x - 2y = -6
<u>Step 2: Solve for </u><em><u>y</u></em>
- Substitute: 2(y - 3) - 2y = -6
- Distribute 2: 2y - 6 - 2y = -6
- Combine like terms: -6 = -6
Here we see that -6 does equal -6. Therefore, any value <em>y</em> would work as a solution. Hence, this systems of equations has an infinite amount of solutions.
