Question

Which of the following is the missing justification?

(3 + 1/3 × x = 7)
Given 1/3 × x = 4 , find x.

(A) Multiplication Property of Equality
(B) Distributive Property
(C) Addition Property of Equality
(D) Subtraction Property of Equality

Answer 1

The missing justification in this problem is the Multiplication Property of Equality. To find the value of x, we can multiply both sides of the equation by 3.

Step-by-step explanation:

The missing justification in this problem is the Multiplication Property of Equality.

To find the value of x, we are given the equation 1/3 × x = 4.

To solve for x, we can multiply both sides of the equation by 3 because multiplication or division by the same number on both sides of an equation does not change equality. This gives us 1/3 × x × 3 = 4 × 3. Simplifying the equation, we have x = 12.
