Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Property

Algebra I

• Solving systems of equations using substitution/elimination

Explanation:

Step 1: Define systems

3x + 3y = 27

x - 3y = -11

Step 2: Solve for x

1. Eliminate y (add equations): 4x = 16
2. Divide 4 on both sides: x = 4

Step 3: Solve for y

1. Define original equation: x - 3y = -11
2. Substitute in x: 4 - 3y = -11
3. Subtract 4 on both sides: -3y = -15
4. Divide -3 on both sides: y = 5
