## First, look at the equations and try to find 2 equations which has the same coefficient (plus or minus) for the same variables. For example, see equations (1) and (3). The coefficient for y is 1 and − 1 respectively. We can add the two equations to eliminate y and we get equation (4).

This calculator (as well as the 2 unknown and 4 unknown calculator) finds the solutions by evaluating determinants using Cramer's rule. The online calculator solves a system of linear equations (with 1,2,,n unknowns), quadratic equation with one unknown variable, cubic equation with one unknown variable, and finally any other equation with one variable. Even if an exact solution does not exist, it calculates a numerical approximation of roots. Calculator Use. Solve for an unknown value x with this fractions calculator.
