Question

3(x + 4) = 18 (Given)

3x + 12 = 18 (Distributive Property)
3x = 6 (Subtraction)
x = 2
Give a reason for the last step in the argument shown.
A)
addition
B)
division
C)
subtraction
D)
multiplication

Answer 1

the answer is division because u divide 3 from both side of the equation so that make the answer B

Answer 2

Answer: The correct answer is B) division.

Explanation:

Hi, to answer this question we have to analyze the information given:

3(x + 4) = 18 (Given)

3x + 12 = 18 (Distributive Property)

3x = 6 (Subtraction)

x = 2

To obtain the result, in the last step we have to divide both sides by 3.

Mathematically speaking:

3x÷3 = 6÷3

x =2

So, the correct answer is B) division.
