To find the value of x, you first need a mathematical equation or expression that includes x. Once you have the equation, you can follow these general steps:
- Step 1: Isolate the variable: Rearrange the equation to get all the x terms on one side and the constants on the other side. This often involves using operations such as addition, subtraction, multiplication, or division.
- Step 2: Solve for x: Once you have isolated x, perform the necessary calculations to solve for its value.
- Step 3: Check your work: It’s always a good idea to substitute your solution back into the original equation to verify that it satisfies the equation.
If the value of x you find is a decimal, you may need to round it to the nearest tenth. To do this, look at the digit in the hundredths place (the second digit to the right of the decimal point):
- If the hundredths place digit is 5 or higher, round the tenths place up by one.
- If the hundredths place digit is less than 5, keep the tenths place the same.
For example, if you find that x = 2.67, you would round it to 2.7 (because 7 is in the tenths place and 6 is in the hundredths place). Conversely, if x = 3.42, you would round it to 3.4.
By following these steps, you can successfully find the value of x and round it as necessary for your problem!
