Question 90561
IT DOES MAKE SENSE. THE SOLUTION IS FOUND BY DRAWING THE 2 LINES AND FINDING THE INTERSECTION.
1.5X-2Y=0 OR -2Y=-1.5X  OR Y=-1.5X/-2 OR Y=.75X (RED LINE)
3X-4Y=7 OR -4Y=-3X+7 OR Y=3X-7 (GREEN LINE)
{{{ graph( 300, 200, -6, 5, -10, 10, y = .75x, y = 3x -7) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = .75x and y = 3x -7). 
sometimes it's difficult to calculate the exact values from the graphing so:
knowing y=.75x we replace y with .75x in the other equation & solve for x:
.75x=3x-7
3x-.75x=7
2.25x=7
x=7/2.25
x=3 1/9 answer
y=3(3 1/9)-7
y=9 3/9-7
y=2 1/3 answer.
