You can put this solution on YOUR website!
5X+Y=12 OR Y=-5X+12 NOW REPLACE Y IN THE OTHER EQUATION WITH (-5X+12)
\n" ); document.write( "2X=3(-5X+12)-19
\n" ); document.write( "2X=-15X+36-19
\n" ); document.write( "2X+15X=17
\n" ); document.write( "17X=17
\n" ); document.write( "X=1 ANSWER.
\n" ); document.write( "5*1+Y=12
\n" ); document.write( "5+Y=12
\n" ); document.write( "Y=12-5
\n" ); document.write( "Y=7 ANSWER.
\n" ); document.write( "PROOF
