Fill in the missing work and justification for step 2 when solving 3(x + 2) = 12.

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

3x+6=12 Distributive Propert

You need to distribute the 3 .

Step-by-step explanation:

    3x + 6 = 12          Subtract 6 on both sides

          3x = 6            Divide both sides by 3

            x = 2

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
