General Formulas and Concepts:

Pre-Algebra

• Distributive Property

Step-by-step explanation:

Step 1: Define

3x + 7 = 3(x + 1)

Step 2: Simplify

1. Distribute 3:                    3x + 7 = 3x + 1

Here we see that the expression 3x + 7 is not equal to 3x + 1.

Answer 2

Answer:

never true

3x+7 = 3 (x+1) < multiply 3 by stuff inside parentheses

3x+7 does not equal 3x+3
