Algebra1 constitutes one of the most important and basic parts of Mathematics. The topic Algebra is sub-divided into different types based on the level of study such as Elementary Algebra, Intermediate Algebra, and Advanced Algebra etc. Algebra1 consists of topics which are for the beginners and it involves topics related to basic operations such as addition, subtraction, multiplication and division in various scenarios such as for expressions and equations etc. In order to do well in math, it is very important to have a good understanding of Algebra1.
Example 1: Simplify the given algebraic expression, 9x + 2 – 5x + 10.
Given expression: 9x + 2 – 5x + 10
In order to simplify the given algebraic expression, we should first combine the like terms together.
The terms containing only ‘x’s, or the terms containing only plain numbers are called as the like terms.
This gives: 9x – 5x + 2 + 10-> 4x + 12
Therefore the simplified form of 9x + 2 – 5x + 10 is = 4x + 12.
Example 2: Find the value of the given algebraic expression, 7x – 5 + 2x – 4 when x = 1.
Given expression: 7x – 5 + 2x – 4
In order to find the value of the given algebraic expression when x = 1, we should just plug-in x = 1 in the given expression.
This gives: 7(1) – 5 + 2(1) – 4==> 7 – 5 + 2 – 4
Calculating the numbers starting from left we get -> 7- 5 +2 -4 = 0
Hence the value of the given expression when x = 1 is 0.
