Simultaneous Equations

What are they?. Simply 2 equationsWith 2 unknownsUsually x and yTo SOLVE the equations means we find values of x and y thatSatisfy BOTH equations [work in]At same time [simultaneously]. Elimination Method. 2x y = 1. 3x y = 9. We have the same number of y's in each. If we ADD the equations,

    1. Simultaneous Equations OCR Module 8

    2. What are they? Simply 2 equations With 2 unknowns Usually x and y To SOLVE the equations means we find values of x and y that Satisfy BOTH equations [work in] At same time [simultaneously]

    3. Elimination Method

    7. Basic steps Look at equations Same number of x’s or y’s? If the sign is different, ADD the equations otherwise subtract tem Then have ONE equation Solve this Substitute answer to get the other CHECK by substitution of BOTH answers

    8. What if NOT same number of x’s or y’s?
