Solve 3x-18=2y and 5x-6y=6 by elimination show work

x =12 and y =9

Step-by-step explanation:

3x -18 = 2y or 3x -2y = 18

 5x-6y = 6

Using elimination method

In order  make coefficient of y in both equation same with different sign ,

we multiply equation 1 by -3 and adding the obtained to equation 2

               -3(3x-2y) = 18x-3

             -9x +6y = -54

              5x -6y =  6

           -----------------------

           -4x       =  -48

             x =

            on plugging the value of y in equation   (1) ,we get

              3(12) -18 = 2y

               36 -18 = 2y

                2y = 18

                y = 18/2  = 9

            x = 12 and y = 9

answer: c

(2, -4)

goes 7 to the

(9, 4)
