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
