Answer:

It has one solution (1,2)

*See attached graph*

Step-by-step explanation:

6x + 3y = 12

y = -2+4

6x + 3y = 12

6x + 3(-2+4) = 12

6x + (-6+12) = 12

6x + 6 =12

     - 6  -6

6x = 6

/6   /6

x = 1

6x + 3y = 12

6(1) + 3y = 12

6 + 3y = 12

-6        -6

3y = 6

/3   /3

y = 2

(x,y) -> (1,2)

Hope this helps!
