Given 2(4x +8) + 3x = 12

Step 1. 8x + 16 + 3x = 12

Step 2. 8x + 3x + 16 = 12

Step 3. 11x + 16 = 12

Step 4. -16 -16

Step 5. 11x = -4

Step 6. /11 /11

Step 7. x = -4/11

Which property justifies between step 2 and step 3?

• Subtraction Property of Equality

• Addition Property of Equality

• Combine Like Terms

• Multiplication Property of Equality
