1x=21 Equation Solution

Are you interested in solving 1x=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 1

To isolate x, we need to divide both sides of the equation by 1. This gives us::

1x
1
=
21
1

Dividing both sides of the equation by 1 is a necessary step to isolate x on one side of the equation. In this case, the coefficient of x is 1, so dividing both sides by 1 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

1 x
1
=
21
1

Simplifying, we get:

x = 21

Step 4: Check the solution

To check if the solution is correct, we can substitute x = 21 back into the original equation:

1x = 21
1 ( 21 ) = 21
21 = 21

Since the equation is true, we know that x = 21 is the correct solution.

So, the solution to 1x = 21 is x = 21

Now that you solved 1x = 21 you can solve another linear equation with one unknown variable here:
