The additive inverse property states that when you add a number to its opposite, the result is always 0. The multiplicative inverse property states that when you multiply any number by its opposite, the result is always 1. The additive property states that when you add any number to zero, the result is the same number. The multiplicative property states that any time you multiply a number by 1, the number does not change.
In order to solve this problem, we must isolate the x on one side of the equation. The first step is to remember that the inverse operations of addition and multiplication are subtraction and division. The next step is to divide both sides by 2, since division is the opposite of multiplication. If you are unsure, you can always go back and check your answer. To do this, substitute 7 for x in the original problem. Get access risk-free for 30 days, just create an account.
First, subtract 9 from both sides: Then multiply each side by 4. Trigonometric functions such as sine, cosine, and tangent also have inverses. They are called the arcsine, arccosine, and arctangent. Inverse trigonometric functions can be used to solve for the angle of a right triangle when you only know the lengths of at least two sides.
For example, say you need to reach the second story window of your house, which is 10 feet off the ground. Your ladder is 18 feet tall. At what angle x do you have to place your ladder to reach the window? Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.

In another words, two operations are said to be inverse of each other, if one of them undoes the effect of another. Addition and Subtraction are inverse operation of each .
In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa.
