9(r) - 7 - 74 = ?
9(r) - 81
You have to solve this part → 9 = ___ [ the answer that goes inside of the blank is '0']
We have to solve this one too! →(r) - 9 = 0
Since, this is the case we have to add ( + ) from the number 9 on each of your sides to make it more simpler
We have one solution in this particular problem..
Therefore, the value of "r" is 9
\(Good Luck !\)
