7x+2y=24 4x+y=15 using elimination

x = 6

y = -9

Step-by-step explanation:

The easiest way is to eliminate y by multiplying equation (2) by -2 and adding to equation (1)

(1)      7x + 2y = 24            (2)     4x + y = 15

       - 8x - 2y = -30                   -8x - 2y = -30

         -x     = - 6

           x = 6                               4(6) + y = 15

                                                    24 + y = 15

                                                            y = - 9
