1. A graphical solution would be achieved by plotting both lines on an x-y graph and seeing where they interesect.

We lack the tools to do graphing for you.

By adding the two equations you can eliminate the y variable and see immediatley that

5x - 15 = 0
x = 3

Then use either of your equations for y.

12 - 3y = 6
3y = 6
y = 2
