The solver of systems of linear equations allows to solve equations with several unknowns: system of equations with 2 unknowns, system of equations with 3 unknowns, system with n unknowns.
Solving equations with several unknowns in other words, solving system of equations online is possible through the use of the function solve_equations of the calculator. The calculator allows the resolution system online of several types, it is possible :
With its ability to algebra, the calculator can solve equations with two unknown or solve equations with 3 unknowns involving letters (literal calculation).
The calculator is an equation system solver that uses a very simple syntax to solve systems of linear equations that admit a single solution.
There are several methods to solve a system of 2 equations with 2 unknowns: the substitution method, the combination method, the graphical method, Cramer's method.
The calculator can use these methods to solve equations with 2 unknowns
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 solve_equations(`[x+y=18;3*y+2*x=46];[x;y]`) ,after calculation, the result [x=8;y=10] is returned.
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.
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 solve_equations(`[x+y+z=1;x-y+z=3;x-y-z=1];[x;y;z]`) , after calculation, the result [x=1;y=-1;z=1] is returned.
