3x-2y=1x+4y=33 elimination process

x = 5 ; y = 7

Step-by-step explanation:

3x - 2y = 1       (I)

 x + 4y  = 33 (II)

Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y

(I)            3x - 2y = 1

(II)*(-3)   -3x -12y = -99         {Now add}

                 - 14y = -98

                        y = -98/14

y = 7

Plugin y = 7  in equation (I)

3x - 2*7 = 1

  3x - 14 = 1

         3x = 1 + 14

         3x = 15

           x = 15/3

x = 5

the discriminant is 64 + 4*1*12 = 112

this is prime.
