Entering data into the Cramer's rule calculator

You can input only integer numbers or fractions in this online calculator. More in-depth information read at these rules

To change the signs from "+" to "-" in equation, enter negative numbers.

If in your equation a some variable is absent, then in this place in the calculator, enter zero.

If before the variable in equation no number then in the appropriate field, enter the number "1".

For example, the linear equation x_{1} - 7x_{2} - x_{4} = 2

can be entered as:

x_{1} + x_{2} + x_{3} + x_{4} =
