Solve_equations(` `), after calculation, the result is returned. Thus for example, to solve the linear system of equations according to x+y+z=1, x-y+z=3, x-y-z=1, it is necessary to enter To find the solutions of the systems of 3 equations with 3 unknowns the calculator can use the substitution method, the combination method or the Cramer method. Solving a system of 3 equations with 3 unknowns Solve_equations(` `) ,after calculation, the result is returned. To solve the system of 2 equations with 2 unknowns according to x+y=18 and 3*y+2*x=46, it is necessary to enter The calculator can use these methods to solve equations with 2 unknowns The graphical calculator makes it possible to carry out this type of operation The graphical method consists in representing the straight lines which correspond to the equations, then 'reading' the coordinates of the point of intersection, The method of graphically solving makes it possible to conjecture the solution which will have to be verified by the calculation,.The substitution method consists of expressing one of the variables as a function of the other and then replacing to arrive at an equation with one unknown.

The combination method consists in eliminating one of the variables thanks to arithmetic operations on the equations.The substitution method, the combination method, the graphical method, Cramer's method. There are several methods to solve a system of 2 equations with 2 unknowns: Solving a system of 2 equations with 2 unknowns The calculator is an equation system solver that uses a very simple syntax to solve systems of linear equations that admit a single solution. With its ability to algebra, the calculator can solve equations with two unknown or solve equations with 3 unknowns involving letters (literal calculation). and more generally, the resolution of online systems equation with several unknowns.
