Question

What is the justification for step 2 in the solution process? 10x − 25 − 3x = 4x − 1 Step 1: 7x − 25 = 4x − 1 Step 2: 7x = 4x + 24

Answer 1

Add 25 to each side using the addition property of equality

Explanation:

10x − 25 − 3x = 4x − 1

Step 1: 7x − 25 = 4x − 1 Combine like terms

Step 2: 7x = 4x + 24 Add 25 to each side using the addition property of equality
