IT DOES MAKE SENSE. THE SOLUTION IS FOUND BY DRAWING THE 2 LINES AND FINDING THE INTERSECTION.
\n" ); document.write( "1.5X-2Y=0 OR -2Y=-1.5X OR Y=-1.5X/-2 OR Y=.75X (RED LINE)
\n" ); document.write( "3X-4Y=7 OR -4Y=-3X+7 OR Y=3X-7 (GREEN LINE)
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+.75x%2C+y+=+3x+-7%29+\" (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = .75x and y = 3x -7).
\n" ); document.write( "sometimes it's difficult to calculate the exact values from the graphing so:
\n" ); document.write( "knowing y=.75x we replace y with .75x in the other equation & solve for x:
\n" ); document.write( ".75x=3x-7
\n" ); document.write( "3x-.75x=7
\n" ); document.write( "2.25x=7
\n" ); document.write( "x=7/2.25
\n" ); document.write( "x=3 1/9 answer
\n" ); document.write( "y=3(3 1/9)-7
\n" ); document.write( "y=9 3/9-7
\n" ); document.write( "y=2 1/3 answer. \n" ); document.write( "
\n" );
