What is the justification for step 2 in the solution process?

gulaghasi [49]

Answer: OPTION B.

Step-by-step explanation:

Given the following equation:

$10x - 25 - 3x = 4x- 1$

These are the steps to solve it:

<em>Step 1</em>

Add like terms on the left side of the equation:

$7x -25= 4x - 1$

<em>Step 2</em>

Apply Addition property of equality, which states that: $If\ a=b\ then\ a+c=b+c$

Then, we can add 25 to both sides of the equation:

$7x -25+(25)= 4x - 1+(25)\\\\7x=4x+24$

<em>Step 3</em>

Applying the Subtraction property of equality, we can subtract $4x$ from both sides:

$7x-4x=4x+24-(4x)\\\\3x=24$

<em>Step 4</em>

Applying the Division property of equality, we can both sides of the equation by 3. Then:

$\frac{3x}{3}=\frac{24}{3}\\\\x=8$
