\n" ); document.write( "solve for x and y by using elimination.
\n" ); document.write( " 3x+5y=-1 |Multiplying 1st EQ by 4, 2nd by 3 and subtracting to eliminate x
\n" ); document.write( " 4x+7y=4 \"x+=+%28-7y%2B4%29%2F4\"
\n" ); document.write( " -y = -16
\n" ); document.write( " y = 16 and x = -27
\n" ); document.write( "and...
\n" ); document.write( "\"3%2A%28-27%29+%2B+5%2A%2816%29+=+-1\" \n" ); document.write( "
