Solving systems of equations using substitution/elimination

Explanation:

Step 1: Define Systems

4x - 2y = 16

4y = -3x + 34

Step 2: Rewrite Systems

4x - 2y = 16

[Multiplication Property of Equality] Multiply everything by 2:                    8x - 4y = 32

Step 3: Redefine Systems

8x - 4y = 32

4y = -3x + 34

Step 4: Solve for x

Elimination

Combine 2 equations:                                                                                    8x = 32 - 3x + 34[Addition] Combine like terms:                                                                      8x = -3x + 66[Addition Property of Equality] Add 3x on both sides:                                 11x = 66[Division Property of Equality] Divide 11 on both sides:                               x = 6
