SOLUTION: Ok guys these graphs are really getting to me :( My new question today is Graph the equation -2.2x+3.9y=-7.8 and -2.7x + 0.9y =7.3 I NEED TO FIND THEIR EXACT INTERSECTION! NO m

Question 305984: Ok guys these graphs are really getting to me :(
My new question today is Graph the equation -2.2x+3.9y=-7.8 and -2.7x + 0.9y =7.3
I NEED TO FIND THEIR EXACT INTERSECTION!
NO matter how many times I try and answer it myself it is wrong!
Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
your looking for the 1 point where the intersection is so the x and the y have to be the same for both equations. so solve for x and then y either by substitution or elimination.
multiply by 0.9
multiply by 3.9

subtract these 2 equations
