Sys2E (com.blogspot.jorqueraorospeda.sys2e) on Google Play
Sys2E free version that contains no advertising and is fully functional but does not have all the features found in the PRO version .-------------------------------------------------- ------------------------------------------Solve stepper systems of 2 linear equations with 2 unknowns by the methods of substitution, equalization and reduction.The coefficients of the system can be integers , fractions and decimals , for example numbers : 3, -5, 2/7, 8.23 , etc .Once entered correctly the system coefficients can see its resolution by the methods of replacement, reduction and equalization . This step by step as if it were made into a book .In the event that the application is incompatible system implies without any problem.If it's an unknown support system has infinite solutions expressed in terms of a parameter is taken and sets x = t versus t .- In the case of the substitution method the unknown x in the first equation to substitute in the second equation is cleared.- In the case of the method of matching the unknown x of the two equations is cleared then the resulting expressions equal and solve for y.- Finally, in the case of the method of the first equation by reducing the need to add the two equations to the variable and set aside , being able to get the value of x and then substitute in the first equation is multiplied factor .The PRO version also :+ Option to choose the variable / equation to punt on the substitution method .+ Option to choose the variable to clear the igulation method .+ Option to choose to reduce the variable reduction method .
