How do you simplify #(r+6)/(6+r)#?
addition is commutative, so :
Think about it:
Therefore, the numerator and the denominator can cancel each other out to have a total value of
Since rhe result of addition does not depend on the order of operands we can write that:
Knowing that we can write that:
The above equality is true for all
We have the same thing on the numerator and the same thing on the denominator, thus this expression is equal to
The terms would cancel with each other, and we would essentially be left with a
Hope this helps!
