25 ++ 5x-9=1/y x 1/y=3 by elimination method 423926-5x-9=1/y x+1/y=3 by elimination method
2 y = 4 2 Hence, y = 2 Therefore, x = 1 and y = 2 is the solution of the set of equations 2x y = 4 and 5x – 3y = 1 Elimination Method Examples Take a look at the elimination method questions Example 1 Solve the following equations using the addition method 2x y = 9 3x – y = 16 Solution If you add down, the y variablesIs 11 You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 – y = 9 5x-9=1/y x+1/y=3 by elimination method
