Simultaneous Equations
... If a pair of simultaneous equations contain an x term which are exactly the same, we can solve them by elimination. When the signs of the equal terms are DIFFERENT, we ADD together the two equations to eliminate x. The same method can be used if the y – terms are equal. (Or for that matter any lett ...
