Question

Name the property illustrated by the statement:

If d+1=f, then d=f-1 .

It's a property of equality, but I'm not sure which one. Please explain which one it is and why it's that one. Thanks! :-)

Answer 1

This is most likely the transitive property. The transitive property states a=b and b=c. which means a=c. It's merely stating that the functions are equal!!

Answer 2

subtraction property of equality.

Explanation:

IF any number is added on both sides of equation then it is addition property of equality.

If any number is subtracted from both sides of the equation then it is subtraction property of equality.

If d+1=f, then d=f-1 .

`d+1=f`

To get 'd' alone , 1 is subtract from both sides

`d=f-1`

1 is subtract from both sides of the given equation.

So it subtraction property of equality.
