Solving Equations Using the Addition Principle Video & Lesson
An addition equation shows the sum of two numbers using + and = signs. The equals sign (=) means the things to its left (๐) are equal to the things to its right (๐). The plus sign (+) shows you what things to add. Writing Equations from Pictures Can you write an addition equation for this picture? Let's do it together! ๐
How to Solve OneStep Equations (Addition & Subtraction)
Addition and subtraction are inverse operations Inverse operations are opposite operations that undo or counteract each other. Here's an example of how subtraction is the inverse operation of addition: If we start with seven, add three, then subtract three, we get back to seven: 7 + 3 โ 3 = 7

An addition sentence is a mathematical expression that shows two or more values added together and their sum. The two or more values that are added are called addends. The parts of addition sentence are two or more addends, plus symbol (s), equal sign, and the sum. Let's look at this with the help of another example.

The Addition Method. Given a system of two linear equations in two variables, we can use the following steps to solve by addition (elimination). Step 1. Choose a variable to eliminate. (Choose the variable with the variable terms with opposite signs, same coefficient, or both, if possible.) Step 2.

Addition equations
x + a โ a = x. x + a โ a = x. The inverse of subtraction is addition. If we start with a number x and subtract a number a, then adding a to the result will return us to the original number x. In symbols, x โ a + a = x. x โ a + a = x. Example 5. Solve x โ 8 = 10 x โ 8 = 10 for x.

About Transcript In this lesson, we learn how to solve simple equations with one unknown variable. To find the unknown, we remove extra numbers by doing the opposite operation on both sides of the equation. This keeps the equation balanced and helps us find the value of the unknown variable.

Students learn to solve one-step addition equations. For example, to solve a + 2 = 7, subtract 2 from both sides of the equation, to get a = 5. Next, check the solution by substituting a 5 back into the original equation, to get (5) + 2 = 7, which is a true statement, so the solution checks. We help you determine the exact lessons you need.
