If x = y then 3x = 3y property of equality

The property of equality that was applied is: multiplication property of equality.

Given:

If

then,

Recall:

The multiplication property of equality states that: if a, b, and n are real numbers, and:

, therefore:

This implies that both sides of an equation will remain the same when both sides are multiplied by the same value.

Therefore, the property of equality that is applied to the equation such that is the multiplication property of equality.

Multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.
