PLS HELP ME SOLVE USING ELIMINATION

Answer 1

Answer:

(0, -3)

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Algebra I

• Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

x - 4y = 12

x - 5y = 15

Step 2: Solve for y

Elimination

1. Subtract 2 equations:                    y = -3

Step 3: Solve for x

1. Define original equation:                    x - 4y = 12
2. Substitute in y:                                     x - 4(-3) = 12
3. Multiply:                                                x + 12 = 12
4. Subtract 12 on both sides:                  x = 0
