How do you solve equations and inequalities examples?

Answer 1

First, you must learn to solve equations, since inequalities have some additional complications.Solving equations may require many different methods; but the main method for simple equations is to do the same manipulation on both sides of the equation (e.g., add a number, multiply by a number, etc.), with the objective of having the variable alone on one side. Here is an example:

2x + 1 = 11

The objective is to have the "x" alone on one side, so you need to get rid of the "2" and of the "1" on the left side. It's easier if you first subtract 1 on each side, with the result:

2x = 10

Now you still need to get rid of the "2" on the left (remember, the objective is to have the "x" alone), so you can divide both sides by 2, with the result:

x = 5

That's the solution.
