You can put this solution on YOUR website!
YOU HAVE 2 CHOICES HERE:
\n" ); document.write( "YOU CAN MULTIPLY THE FIRST EQUATION BY 2 (ELIMINATE THE Y TERM OR MULTIPLY THE SECOND EQUATION BY -3 (ELIMINATES THE X TERM)& THEN ADD THEM.
\n" ); document.write( ".36X+.54Y=.18
\n" ); document.write( ".06X-.54Y=-.04 NOW ADD:
\n" ); document.write( "-----------------------------------
\n" ); document.write( ".42X=.14
\n" ); document.write( "X=.14/.42
\n" ); document.write( "X=1/3 ANSWER.
\n" ); document.write( "NOW REPLACE X BY 1/3 & SOLVE FOR Y.
\n" ); document.write( ".06*1/3-.54Y=-.04
\n" ); document.write( ".02-.54Y=-.04
\n" ); document.write( "-.54Y=-.04-.02
\n" ); document.write( "-.54Y=-.06
\n" ); document.write( "Y=-.06/-.54
\n" ); document.write( "Y=1/9 ANSWER.
\n" ); document.write( "PROOF
\n" ); document.write( ".18*1/3+.27*1/9=.09
\n" ); document.write( ".06+.03=.09
\n" ); document.write( ".09=.09\r
