An inverse is another word for opposite. The inverse for adding is subtraction, multiplication is division, etc. If you are solving an equation, and have to get a variable alone, you must eliminate any other numbers with the variable, which means undoing the operation (x, +, -, /); so you perform the inverse.
Example:
x + 3 = 9.
Subtract 3 on both sides to get x alone, because subtraction is the inverse of addition:
x = 6.
Example:
2x + 3 = 9.
You must do the inverse of addition and subtraction before the inverse of multiplication and division. In this case, after subtracting 3 you have:
2x = 6.
x is being multiplied by 2, so the inverse is division, and your answer is x = 3.
