Pair of Linear Equations In Two Variables Important Questions

WebFor a system of two linear equations and two variables, there can be no solution, exactly one solution, or infinitely many solutions (just like for one linear equation in one variable). If the two equations are in standard form (both variables on one side and a constant on the other side), then the following are true: WebElimination Method Steps. Step 1: Firstly, multiply both the given equations by some suitable non-zero constants to make the coefficients of any one of the variables (either x or y) numerically equal. Step 2: After that, add or subtract one equation from the other in such a way that one variable gets eliminated. project sarathi uppcl
