CalcES calculator allow you to find roots of system equations with 2, 3 and 4 unknown variables.
Example 1:
5x + 3y = 7
3x - 5y = -25
Example 2: system of equations of 3 variables: x, y, z
x + y + z = 25
5x + 3y + 2z = 0
y - z = 6
Example 4: system of equations of 4 variables: x, y, z, t
2a + 2b - c + d = 4
4a + 3b - c + 2d = 6
8a + 5b - 3c + 4d = 12
3a + 3b - 2c + 2d = 6
Example: solve system of equations
5x + 3y = 7
3x - 5y = -25
