Answer:

(x,y) = (6,4)

Step-by-step explanation:

-x+3y=6

x+3y =18

using elimination method

eliminate 1 variable, by adding equations

add the equations vertically

6y = 24

divide by 6 on both sides

6y/6 = 24/6

y = 4

NOT DONE YET!

substitute the y value

-x + 3(4) = 6

x = 6

(x,y) = (6,4)

CHECK:

-6 + 3(4) = 6

6 + 3(4) = 18

6 = 6

18 = 18
