All you have to do is, if it is multiplication.....
9x = 27
divide by 9 on both sides
to take the variable away 9 dived by 9 is 1 in this case its 0 because here 1 is worth nothing. and 27 divided by 9 is 3 so
x= 3
it is the same with addition or subtraction.
9+x=27
all you do here is subtract 9 on both sides so 9-9=0
and 27-9= 18
so x= 18
all you have to do is find the opposite ways
addition is opposite of subtraction
and multiplication is the opposite of division!

How do you use inverse operation?
Definition of Inverse OperationTwo operations are said to be Inverse to each other if one operation undoes the effect of the other operation.More about Inverse OperationAddition and subtraction are inverse operations of each other.Multiplication and division are inverse operations of each other.Examples of Inverse OperationThe inverse operation of "10 + 9 = 19" is "19 - 9 = 10", or vice-versa.The inverse operation of "7 × 9 = 63" is "63 ÷ 9 = 7", or vice-versa.Solved Example on Inverse OperationQ. The inverse operation for 14 × 4 = 56. A. 56 ÷ 4 = 14

How do you use the inverse operation to add 23?
Using the inverse operation is probably the most clumsy way of obtaining the answer.To add 23 to some known number x, you would be required to find the number y such that subtracting 23 from y (the inverse operation) would result in x. Why on earth would you do that?
How can you use the inverse operation to check your answers?
Just apply the inverse operation to your answer. If your answer was correct, and you apply the inverse operation correctly, then you'll end up with the numbers you started with ... the numbers in the original problem. (If it wasn't, or you don't, then you won't.)
When do people use inverse operation?
people use inverse operations when there is a number like -3 then you change it to a regular problem like 3. you use it when something is opposite to the regular problem.
Where is the inv button on the scientific calculator?
It means inverse, and performs the opposite of the given operation. For example, if you want inverse of tangent, you will use that inv button.

The sum of an integer and its inverse is 0?
The sum of a number and its inverse is 0, because that's what "its inverse" means. Inverse is whatever you need to use to "undo" the operation. For example, (2)+(-2)=0. If you go forward 2, then backward 2, you are where you started.
How does the inverse operation affect solving an equation?
It affects because if you want to solve a multiplication problem you can use it or also to check your division problem
