(3/4)x + (1/3)y = (3/2) multiply by 2.
\n" ); document.write( "(1/2)x + (5/6)y = (21/2) multiply by -3 & add.
\n" ); document.write( "1.5x+2/3y=3
\n" ); document.write( "-1.5x-15/6y=-63/2
\n" ); document.write( "--------------------
\n" ); document.write( "2y/3-15y/6=3-63/2
\n" ); document.write( "(2y*2-15y)/6=(3*2-63)/2
\n" ); document.write( "(4y-15y)/6=(6-63)/2
\n" ); document.write( "-11y/6=-57/2
