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:

Step 1

Add like terms on the left side of the equation:

$7x -25= 4x - 1$

Step 2

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:

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

Step 3

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

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

Step 4

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

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

What times 3/8 equals 1 whole

Elis [28]

$\frac{8}{3}$ times $\frac{3}{8}$ equals 1

Solution:

Given expression is at what times $\frac{3}{8}$ equals the whole.

Whole means 1 in a fraction.

Let us take the number of times be x.

$x\times\frac{3}{8} =1$

Multiply by $\frac{8}{3}$ on both sides of the equation.

$x\times\frac{3}{8}\times\frac{8}{3} =1\times\frac{8}{3}$

$x\times\frac{24}{24} =1\times\frac{8}{3}$

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

$x\times1 =\frac{8}{3}$

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

Hence the fraction $\frac{8}{3}$ times $\frac{3}{8}$ equals 1.
