Stepper Solve two linear equations systems with 2 unknowns by the methods of substitution, equalization and reduction.

The coefficients of the system can be integers, fractions and decimals, for example: 3, -5, 2/7, 8.23, etc.

Once entered correctly the system coefficients can see its resolution by the methods of substitution, equalization and reduction. This step by step as if it were made into a book.

In the case of the system indicates incompatible application without any problem.

If it is indeterminate compatible system has infinite solutions expressed in terms of a parameter, is taken and put x = t versus t. In case it does not possible backwards, ie x = ty takes places and according to t.

- In the case of the substitution method first tries to clear the unknown x in the first equation to substitute into the second equation. If this is not possible because the coefficient for x is 0 then try and clear the.

- In the case of matching method clears the unknown x from the two equations and then the resulting expressions equal and solve for y. If you can not isolate x in both equations tries to clear the y if this is not possible then it indicates that the system can not be solved by this method.

- In the case of the first reduction method that tries to eliminate the variable 'and' multiplying the first equation by the coefficient of 'and' in the second and multiplying the second equation by the coefficient opposite 'and' the first. In this way by adding the resulting equations will eliminate the 'y'. Should be one of these coefficients used 0, analogous attempts to remove the 'x'.

If true system can not be solved by a particular method indicates.

Solve all cases of indeterminate compatible systems.
