2x-3y=15
\n" ); document.write( "x+y=6
\n" ); document.write( "multiply by 3
\n" ); document.write( "3x+3y=18
\n" ); document.write( "add this equation to the first equation
\n" ); document.write( "3x+2x+3y-3y=15+18
\n" ); document.write( "5x=33
\n" ); document.write( "x= 33/5
\n" ); document.write( "..
\n" ); document.write( "plug value og x in second equation
\n" ); document.write( "..
\n" ); document.write( "33/5 +y = 6
\n" ); document.write( "33+5y / 5 =6
\n" ); document.write( "33+5y = 30
\n" ); document.write( "5y=30-33
\n" ); document.write( "5y=-3
\n" ); document.write( "/5
\n" ); document.write( "y = -3/5
\n" ); document.write( "..
