the division property of equality

the addition property of equality

the subtraction property of equality

Answer 1

I think it would be the Multiplication property of equality

Answer 2

Answer:

A.The multiplication property  of equality

Step-by-step explanation:

We are given that

If x=3 then $x^2=3x$

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

Let p: x=3

q:$x^2=3x$

There is q is conclusion is $x^2=3x$

If we multiply by x on both sides then we get

$x\cdot x=3\cdot x$

$x^2=3x$

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

Answer:A.The multiplication property  of equality
