In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
Hope this helps!

elimantion method in elimantion method, the coffecients of the given equations are mulitiplied by a constant to make the coffiecents of one variable in the same in both equations. Finally any one variable remains at the end, which can then be easily solved.
