... The elimination method – Example 1 If two equations are true for the same values, we can add or subtract them to give a third equation that is also true for the same values. For example, suppose 3x + y = 9 5x – y = 7 Adding these equations: 3x + y = 9 + 5x – y = 7 8x divide both sides by 8: ...
