What is x if x + 3x + 5x = 45?

Question

Here is the question : WHAT IS X IF X + 3X + 5X = 45?

Option

Here is the option for the question :

  • 1
  • 5
  • 9
  • 15

The Answer:

And, the answer for the the question is :

5

Explanation:

Given that there is only one variable in this equation, you can simply take the values x, 3x, and 5x and add them all up to get the value 9x. Since 9x equals 45, all that needs to be done to get the value of x, which is 5, is to divide both sides of the equation by 9.

What is x if x + 3x + 5x = 45?
In mathematics, equations are used to represent relationships between different variables. One common type of equation is the linear equation, which involves only one variable and can be written in the form of ax + b = c, where x is the variable, a is the coefficient of x, b is a constant term, and c is another constant.

In the equation given, x + 3x + 5x = 45, we have three terms that involve the variable x, each with a different coefficient. To solve for x, we need to simplify the equation by combining like terms on the left-hand side. Adding the coefficients of x gives us 9x, so we can rewrite the equation as 9x = 45.

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 9, which gives us x = 5. Therefore, the solution to the equation x + 3x + 5x = 45 is x = 5.

This type of equation is commonly used in many areas of mathematics, as well as in physics, engineering, economics, and other fields. It is important to be able to solve linear equations quickly and accurately, as they are often used to model real-world situations.

there are many other types of equations that involve multiple variables, exponents, logarithms, and other mathematical operations. These equations can be more complex to solve, but they are also useful in many applications.

the ability to solve equations is a fundamental skill in mathematics and is essential for success in many fields. By understanding the basic principles of algebra and practicing solving equations, students can develop the skills needed to tackle more complex problems and achieve their academic and professional goals.
