3x3 Cramers rule calculator provided at the end of this web page will give
you the solution for any system of three linear equations, if exists. As soon as
you enter your matrix in the boxes provided and click the button "calculate", will give
you the solution for any system of three linear equations, if exists. Further instructions related to this calculator at the end of this web page.

Why do people need this calculator?

Apart from the regular calculator, people who study math are in need of 3x3 Cramer's rule calculator. Because, when people work out lengthy
problems,
they may not have time to solve the system of three linear equations by Cramer's rule. At that
time, solving for the given variables would be an additional
burden for them in
solving lengthy math problems. To reduce the burden of those people, we
have provided this Cramers rule calculator for 3 equations here.

Using the calculator in solving word problems

When people do preparation of solving word problems on matrix,
they may have to spend time to get idea on "How to solve". In this
situation, they would not like to spend time to solve for the given variables using Cramer's rule. And also they would not be able to use the
regular
calculators to inverse of a matrix. By using this
online calculator, students
will find much time to get idea of solving the word problems.

Advantages of using this inverse calculator

School students have the topic "Solve the system of equations using Cramer's rule" in their 11th and 12th grades. They are given a system of simultaneous equations and they have to solve for
the variables which are in the equations using Cramer's rule.They will solve the problem as directed in the question. But they are not sure
whether the answer they got is correct or incorrect. At that time, they
can check the answer they have received is correct or incorrect using
this calculator. .

Apart from the
advantages explained above, this calculator can also be used to learn
how to solve the system of simultaneous equations using Cramer's rule.

When students solve the system of three equations using Cramer's rule, they have to find many values like delta, delta x , delta y and delta z. When student find the above four values, if they do mistake in finding even in one of those four values, they will not get the correct answer. And also, it is bit difficult to check where the mistake has been done. At that time, students can use this 3x3 Cramers rule calculator and they can come to know where they have done mistake.
