You can put this solution on YOUR website!
3x + 5y = 44 multiply by 7
\n" ); document.write( "8x - 7y = -25 multiply by 5 & then add.2
\n" ); document.write( "21x+35y=308
\n" ); document.write( "40x-35y=-125
\n" ); document.write( "-------------------
\n" ); document.write( "61x=183
\n" ); document.write( "x=183/61
\n" ); document.write( "x=3 ans.
\n" ); document.write( "3*3+5y=44
\n" ); document.write( "9+5y=44
\n" ); document.write( "5y=44-9
\n" ); document.write( "5y=35
\n" ); document.write( "y=35/5
\n" ); document.write( "y=7 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "8*3-7*7=-25
\n" ); document.write( "24-49=-25
\n" ); document.write( "-25=-25 \n" ); document.write( "

\n" );
