\n" );
document.write( "6x-2y=-4     ||Substitute for y and find x ( then y = 5x)\r
\n" );
document.write( "\n" );
document.write( " ||Substitute for x and find y (then  x = 8-2y)
\n" );
document.write( "4x-y=5 \r
\n" );
document.write( "\n" );
document.write( "-7x+y=32    || Multiply 1st EQ by -3 and add to eliminate y (you'll find x =-3
\n" );
document.write( "2x+3y=27\r
\n" );
document.write( "\n" );
document.write( "2x+y=5      || Multiply 1st EQ by 3 and add to eliminate y  (you'll find x =1/2
\n" );
document.write( "4x-3y=-10 \r
\n" );
document.write( "\n" );
document.write( "4x+2y=7  
\n" );
document.write( "x-5y=10     || Multiply 2nd EQ by -4 and add to eliminate x (you'll find y = -3/2 \n" );
