Simultaneous Equations With Three Unknowns Youtube This algebra video tutorial shows you how to solve simultaneous equations using the substitution method, the elimination method, graphical method, systems of. Click here for answers. practice questions. previous: fm simultaneous equations (non linear) questions. next: fm laws of indices questions. the corbettmaths practice questions on simultaneous equations (3 unknowns) for level 2 further maths. The strategy is to reduce this to two equations in two unknowns. do that by eliminating one of the unknowns from two pairs of equations: either from equations 1) and 2), or 1) and 3), or 2) and 3). for example, let us eliminate z. we will first eliminate it from equations 1) and 3) simply by adding them. we obtain: 4) 3x 4y = 11. Worked example. solve the simultaneous equations. method 1: elimination. number the equations. eliminate by adding equations (1) and (2). (1) (2): find a second equation in and by subtracting 2 times equation (1) from equation (3). (3) 2 (1): solve equations (4) and (5) using your preferred method of solving a pair of linear simultaneous.
