X+Y=11 THEN X=11-Y & X-Y=5 NOW SUBSTITUTE (11-Y) FOR X IN THE SECOND EQUATION & SOLVE FOR Y:
\n" ); document.write( "(11-Y)-Y=5
\n" ); document.write( "11-Y-Y=5
\n" ); document.write( "-2Y=5-11
\n" ); document.write( "-2Y=-6
\n" ); document.write( "Y=-6/-2
\n" ); document.write( "Y=3 ANSWER.
\n" ); document.write( "X+3=11
\n" ); document.write( "X=11-3
\n" ); document.write( "X=8 ANSWER.
\n" ); document.write( "PROOF
\n" ); document.write( "3*8=24
\n" ); document.write( "24=24\r
