Step Work Justification
1 3(x + 2) = 12 Given
2
3 3x + 6 − 6 = 12 − 6 Subtraction Property of Equality
4 3x = 6 Simplify
5 Three times x over three equals six over three Division Property of Equality
6 x = 2 Simplify
3x + 6 = 12; Distributive Property
3x + 2 = 12; Distributive Property
3x + 6 = 12; Multiplication Property of Equality
3x + 2 = 12; Multiplication Property of Equality

Answer 1

Answer:

3x+6=12 Distributive Propert

Answer 2

Answer:

You need to distribute the 3 .

Step-by-step explanation:

3 ( x + 2 ) = 12          Distribute

    3x + 6 = 12          Subtract 6 on both sides

          3x = 6            Divide both sides by 3

            x = 2
