Solve the system below by the elimation

7x+2y=24

8x+2y=30

x = 6

y = - 9

Step-by-step explanation:

multiply first equation by - 1

-1 * (7x + 2y) = 24 ➡ - 7x-2y = - 24

now add this to the second equation

-7x-2y + 8x + 2y = 30-24

x = 6

use thus value to find y

8*6 + 2y = 30 ➡2y = 30-48

y = - 9
