10x=21 Equation Solution

Are you interested in solving 10x=21 for x? We will walk you through the calculation steps and show you how to isolate x so that you can find the value that solves this equation.


Step 1: Isolate the variable

The goal is to find the value of x. To do this, we need to isolate x on one side of the equation.


Step 2: Divide by 10

To isolate x, we need to divide both sides of the equation by 10. This gives us::

10x
10
=
21
10

Dividing both sides of the equation by 10 is a necessary step to isolate x on one side of the equation. In this case, the coefficient of x is 10, so dividing both sides by 10 will cancel out the coefficient on the left side.


Step 3: Simplify the equation

Next step is to simplify the equation which allows us to solve for x and find its value in the given equation

10 x
10
=
21
10

Simplifying, we get:

x = 2.1

Step 4: Check the solution

To check if the solution is correct, we can substitute x = 2.1 back into the original equation:

10x = 21
10 ( 2.1 ) = 21
21 = 21

Since the equation is true, we know that x = 2.1 is the correct solution.

So, the solution to 10x = 21 is x = 2.1

Now that you solved 10x = 21 you can solve another linear equation with one unknown variable here:
