Answer:

x = 2

y = 7

Step-by-step explanation:

5x+2y=24  -------------->equ 1

8x+2y=30 -----------> equ 2

equ 1 - equ 2 =====>         -3x = - 6

                                               x = -6 / -3  = 2

                                               x = 2

Put x = 2 in equ 1,  

 5*2 + 2y = 24

10 + 2y = 24

        2y = 24 - 10

         2y = 14

            y = 14/2

            y = 7
