Question

Name the property of equality that justifies & Name the property of equality that justifies: If x + 3 = 5, then x = 2.

Answer 1

A) In this question two angles are given equal and in next step both sides are multiplied by 5 and the result of both sides is equal to each other. The property used is

"When equal are multiplied by equL number then the result is also equal" the equality property is of multiplication.

B) In this question $x+3=5$ is given

And then $x=2$

Here number 3 is subtaracted from both the sides to make $x$ equal to 2.

The property of equality used is " If equal are subtracted from equal the result will be equal"

Here the equality property of subtraction is uaed.
