the multiplication property of equality

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

A.The multiplication property of equality

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
