what is the resolution to the following prob.: y=-2/5x-2 and y=9/5x+7

y= (-2/5)x-2 and y=(9/5)x+7

Let's just set these equal

(-2/5)x - 2  =  (9/5)x + 7     subtract 7 from both sides, add (2/5)x to both sides

-9  =  [ 9/5 + 2/5] x   simplify

-9  = [11/5]x     multiply both sides by 5/11

-9 (5/11) = x  = -45/11
