Read full descriptionHide full description
This application helps students or any person who needs, to solve a system of 3 linear equation with 3 unknowns. A system of linear equations is of this type: / | a11.x + a12.y + a13.z = c1 | a21.x + a22.y + a23.z = c2 | a31.x + a32.y + a33.z = c3 \ Values are required for x,y,z which satisfy the 3 equations. In the application skema, insert the matrix coefficients: a11 a12 a13 a21 a22 a23 a31 a32 a33 and next insert the constant values: c1 c2 c3 Finally, hit the Solve button. If the system has a real solution, this will be shown (x,y,z) in the last row. If no real solution exists, NO,NO,NO will be shown.
