Solving Simultaneous Equations: Elimination Method Multiple one, or both, of the equations by suitable multiplier, until they have a matching number of x's or y's 2 variants of method: If the matching terms have one + and one - signs, then use add equations. If signs are the same then subtract equations. Remember: DASS : Different, Add; Same, Substract! Solving Simultaneous Equations: Graphical Method Use if answers are whole numbers. Example: 4x + y = 6 equation(1) 5x-4y = ...
