A KS3-4 resource on simultaneous equations that illustrates the elimination process, by equalizing the first term (usually x) every time.
It always involves subtraction so the decision as to whether to add or subtract is removed.
Two examples are shown, with step-by-step description and then four questions are given for students to answer.
