solve by elimination
we can see that we can eliminate y from both equations by mulitpying the 2nd equation by 2 and adding them
x+6y=1
4x-6y=64 +
5x+0y=65
5x=65
divide both sides by 5
x=13
subsitute back
x+6y=1
13+6y=1
minus 13 both sides
6y=-12
divide by 6 both sides
y=-2
solution is x=13 and y=-2 or (13,-2) is the solution
