\n" ); document.write( "x+y=13 multiply this equation by -22 & add.
\n" ); document.write( "22x+36y=356
\n" ); document.write( "-22x-22y=-286
\n" ); document.write( "-----------------------
\n" ); document.write( "0+14y=70
\n" ); document.write( "y=70/14
\n" ); document.write( "y=5 answer.
\n" ); document.write( "x+5=13
\n" ); document.write( "x=13-5
\n" ); document.write( "x=8 answer.
\n" ); document.write( "proof:
\n" ); document.write( "22*8+36*5=356
