Select the property of equality used to arrive at the conclusion. if x = 3, then x 2 = 3x the multiplication property of equality the division property of equality the addition property of equality the subtraction property of equality

A.The multiplication property  of equality

Step-by-step explanation:

We are given that

If x=3 then

We have to find that which property of equality used to arrive at  the conclusion.

Let p: x=3

q:

There is q is conclusion is

If we multiply by x on both sides then we get

Hence, the multiplication property  of equality used to arrive at the conclusion.

A.The multiplication property  of equality

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
