Solve by either graphing and then get an exact solution by using either substitution or elimination:

both are straight lines. For x = 0 find y for both equations and mark those points on a graph
Then for x = something else, like 10, find y for both equations
draw lines through the points for each equation
Find where the lines cross.
x = (3y+6)
substitute that in the second one
2(3y+6) + y = 2
