This is a question about equations with one variable. We have to solve this calculation to obtain the value of N. Our task is to isolate the variable N alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposite side.
Let's arrange it into an equation, i.e.,
Turn this equation over so that the position of variable N is on the left side.
Both sides are multiplied by 10 to isolate N on the left side.
N = 900
Therefore, we have determined the number that was asked.
Hence,
<u>Note: </u>
The important thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:
- Adding,
- Subtracting,
- Multiplying, and/or
- Dividing both sides of the equation with a similar number.
And, last but not least, the commutative property of multiplication
