21x=3 Equation Solution
Are you interested in solving 21x=3 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 21
To isolate x, we need to divide both sides of the equation by 21. This gives us::
Dividing both sides of the equation by 21 is a necessary step to isolate x on one side of the equation. In this case, the coefficient of x is 21, so dividing both sides by 21 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
Simplifying, we get:
Step 4: Check the solution
To check if the solution is correct, we can substitute x = 0.14 back into the original equation:
21 ( 0.14 ) = 3
3 = 3
Since the equation is true, we know that x = 0.14 is the correct solution.
Now that you solved 21x = 3 you can solve another linear equation with one unknown variable here:
