Having the ability to quickly find x and round the answer to the nearest integer is a crucial skill for those who understand mathematics or coding. Not only can finding x and rounding it help you make calculations faster, but it can also be a necessary step in many calculations. In this guide, we will help you understand how to find x and round the answer to the nearest integer.
Finding x is not as difficult as it may sound, and is actually quite a simple mathematical process. To find x, simply begin by considering the equation presented.
Let's use 3x-2=6 as an example equation. In this example, you want to solve for x.
To begin to solve for x, you will need to add 2 to both sides of the equation. This process is called “isolation” because you are looking to isolate the x, or the unknown variable.
To finish solving for x, you will need to divide both sides of the equation by 3.
x=8/3 or 2.6666
Rounding the Answer to the Nearest Integer
Now that you know how to find x, and have an answer of 2.6666, we can move on to rounding the answer to the nearest integer. When rounding the answer to the nearest integer, you want to examine the number to the right of the decimal and decide if it is less than (.5) or more than (.5).
In this example, the answer is 2.6666. The number to the right of the decimal is .6666, which is larger than .5.
This means that you will want to round the answer up, so the final answer will be 3.
What is an Integer?
An integer is a whole number (not a fraction) that can be positive, negative, or zero. For example, 7 is an integer, but 7.5 and 7/5 are not.
What is Isolation?
Isolation is the process of removing all terms and isolating a variable to make it easier to find a solution. When isolating a variable, you are essentially changing it to the opposite operation while ensuring that both sides of the equation remain equal.
What is an Equation?
An equation is a sentence or statement that states that two things are equal. Equations are written using an equal sign, and can involve any combination of numbers, variables, and operations (addition, subtraction, multiplication, division).
What is X?
X is a variable, or symbol used in mathematics to represent an unspecified value in an equation.
How Do I Round a Number?
To round a number, look at the number to the right of the decimal and decide if it is less than (.5) or more than (.5). If the number is less than (.5), round the answer down, whereas if the answer is more than (.5), round the answer up.
