2x + y =20
6x - 5y = 12
Solve as a whole number

x = 7, y = 6

(7,6)

Step-by-step explanation:

2x + y =20

6x - 5y = 12

2x + y = 20

-2x     -2x

y = -2x + 20

6x - 5y = 12

6x - 5(-2x + 20) = 12

6x + 10x - 100 = 12

16x - 100 = 12

     + 100  +100

16x = 112

/16    /16

x = 7

Now, we solve for y:

2x + y = 20

2(7) + y = 20

14 + y = 20

-14      -14

y = 6

(x, y) -> (7,6)
