• Solving systems of equation using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

3y = -5x - 3

y = -x + 1

Step 2: Rewrite Systems

Equation y = -x + 1

1. [Multiplication Property of Equality] Multiply everything by -3:                   -3y = 3x - 3

Step 3: Redefine Systems

3y = -5x - 3

-3y = 3x - 3

Step 4: Solve for x

Elimination

1. Combine 2 equations:                                                                                   0 = -2x - 6
2. [Addition Property of Equality] Add 6 on both sides:                                  6 = -2x
3. [Division Property of Equality] Divide -2 on both sides:                              -3 = x

Step 5: Solve for y

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