  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4x + 5y = -12

-2x + 3y = -16

Step 2: Rewrite Systems

-2x + 3y = -16

  1. Multiply everything by 2:                    -4x + 6y = -32

Step 3: Redefine Systems

4x + 5y = -12

-4x + 6y = -32

Step 4: Solve for y

Elimination

  1. Combine 2 equations:                    11y = -44
  2. Divide 17 on both sides:                  y = -4
