WebMethod of Substitution. Step 1: Solve one of the equations for one variable. Step 2: Substitute this in the other equation to get an equation in terms of a single variable. Step … WebWe now wish to add the two equations but it will not result in either x or y being eliminated. Therefore we must multiply the second equation by 2 on both sides and get: $$2x-2y=8$$ $$2x+2y=2$$ Now we attempt to add our system of equations. We commence with the x-terms on the left, and the y-terms thereafter and finally with the numbers on the ...
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. WebTo add the widget to iGoogle, click here.On the next page click the "Add" button.
