6x + 5y = 10 multiply by 3.
\n" ); document.write( "7x – 3y = 24 multiply by 5 & add.
\n" ); document.write( "18x+15y=30
\n" ); document.write( "35x-15y=120 add.
\n" ); document.write( "-----------------
\n" ); document.write( "53x=150
\n" ); document.write( "x=150/53
\n" ); document.write( "x=2.83 ans.
\n" ); document.write( "6*2.83+5y=10
\n" ); document.write( "16.98+5y=10
\n" ); document.write( "5y=10-16.98
\n" ); document.write( "5y=-6.98
\n" ); document.write( "y=-6.98/5
\n" ); document.write( "y=-1.396 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "7*2.83-3*-1.396=24
\n" ); document.write( "19.81+4.17=24
\n" ); document.write( "23.98=24\r
