Question
Here is the question : IF X = 3, WHAT IS 3(3X + 3)?
Option
Here is the option for the question :
- 3
- 6
- 9
- 36
The Answer:
And, the answer for the the question is :
Explanation:
In order to answer this equation, you must first substitute the value 3 for x, resulting in the equation 3((3 x 3) + 3). When solving large equations using algebra, you should always start by solving the part of the equation that is included within the parentheses. Therefore, the following step is to find the answer to the equation 3 x 3, which is 9. You now have 3 (9 plus 3) to work with. Having obtained 12 by adding 9 and 3, the equation is now written as 3(12). Multiplying those two integers together gives you the answer 36; this is the final answer.
Mathematics is a subject that many people find challenging, but it is also a subject that is fundamental to our daily lives. From calculating grocery bills to understanding the stock market, math plays a crucial role in our lives. One of the basic concepts in math is algebra, which involves the use of symbols and equations to solve problems. In this article, we will explore an algebraic equation and learn how to solve it.
The equation in question is “3(3x + 3)” and we are asked to find the value of the expression when x is equal to 3. To solve this equation, we need to understand the order of operations. The order of operations is a set of rules that dictate the order in which mathematical operations are performed. The acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) is often used to remember the order of operations.
In the expression “3(3x + 3)”, we first need to simplify the expression inside the parentheses. To do this, we need to distribute the 3 to both terms inside the parentheses. This gives us:
3(3x + 3) = 9x + 9
Now that we have simplified the expression inside the parentheses, we can apply the multiplication operation to the entire expression. This gives us:
3(3x + 3) = 3(9x + 9) = 27x + 27
Finally, we substitute x with 3, which gives us:
3(3x + 3) = 27x + 27 = 27(3) + 27 = 81
Therefore, the value of the expression “3(3x + 3)” when x is equal to 3 is 81.
It is important to note that the order of operations is crucial in algebraic equations. Failure to follow the correct order of operations can lead to incorrect answers. It is also important to simplify expressions as much as possible before applying operations. This helps in reducing errors and making the calculations easier.
algebra is an essential branch of mathematics that plays a significant role in our lives. The equation “3(3x + 3)” is a simple example of an algebraic expression that can be solved using the order of operations and substitution. By following the correct order of operations and simplifying the expression, we were able to find the value of the expression when x is equal to 3, which is 81.
