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 A. the division property of equality B. the multiplication property of equality C. the subtraction property of equality D. the addition property of equality

Answer 1

Answer:

the awnser is b

Step-by-step explanation:

Answer 2

According to the given questions

We have to find the justification step in the solution.

Step-by-step explanation:

Given ,

The equation of the given questions

$10x − 25 − 3x = 4x − 1$

In that some values are constant and some are with variable x.

STEP-1:

Solve the above equation

$10x − 25 − 3x = 4x − 1$

subtract the variable value on Left hand side,we get

$7x − 25 = 4x − 1$

STEP-2:

Now ,

shift the constant value toward Right hand side, we get

$7x = 4x - 1 + 25$

$7x = 4x - 24$

The justification for the step-2 is the subtraction property of equality.

Further solve the equation

STEP-3:

$7x = 4x - 24$

Shift the variable value toward Left hand side ,

$7x - 4x = - 24$

$3x = - 24$

Shift the value in division as Right hand side ,

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

$x = - 8$

Hence ,

Option ( C)the subtraction property of equality is correct .
