Algebra I

• Terms/Coefficients
• Coordinates (x, y)
• Solving systems of equations using substitution/elimination

Explanation:

Step 1: Define Systems

y = -4x + 1

11y = x + 146

Step 2: Solve for x

Substitution

1. Substitute in y: 11(-4x + 1) = x + 146
2. Distribute 11: -44x + 11 = x + 146
3. [Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146
4. [Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x
5. [Division Property of Equality] Divide 45 on both sides: -3 = x
6. Rewrite/Rearrange: x = -3

Step 3: Solve for y

1. Define original equation: y = -4x + 1
2. Substitute in x: y = -4(-3) + 1
3. Multiply: y = 12 + 1
4. Add: y = 13
