Question

Solution of x-y=3 and x/3+y/2=6 by elimination method

Answer 1

Answer:

x = 9 and y = 6

Step-by-step explanation:

We are given two equations;

        x - y = 3                         and                x/3 + y/2 = 6

      x = 3 + y ------- (1)                                    $\frac{2x + 3y}{6} = 6$

Multiplying whole equation(1) by 2              2*x + 3*y = 36 ------- (2)

     2*x - 2*y = 6

Now,                         2*x + 3*y = 36

                                 2*x - 2*y = 6      

                              (-)     (+)         (-)  

                                      5*y   =  30

                                        y   = 30/5 = 6

Now, putting value of y in (1), we get x = 3 + 6 = 9

Therefore, using elimination method x = 9 and y = 6.
