This is for (14)okay, so basically this is a system of linear equations. NOT SURE ABOUT 15!

{y=3x
{x=3y
and you have to come up with a solution (a coordinate) that works for both equations.
so you can substitute the first equation into the second equation.
so, x=3(3x)....... Use Distributive Property x=9x . Subtract x from both sides
0=8x .Divide 8 by both sides to isolate x
0=x

okay, now plug in x=0 into the first equation
... y=3(0) ....... Use Distributive Property
... y=0
Now that you have solved for x and y, you have finally found your coordinate (x,y): x=0 and y=0, so your coordinate and solution to this problem is (0,0)
