You can put this solution on YOUR website!
3 x + 6 y = 15 .............1
\n" ); document.write( "-2 x + 3 y = -3 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -2
\n" ); document.write( "3 x + 6 y = 15
\n" ); document.write( "4 x + -6 y = 6
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 x = 21
\n" ); document.write( "/ 7
\n" ); document.write( "x = 3
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 6 y = 15
\n" ); document.write( "9 + 6 y = 15
\n" ); document.write( " 6 y = 15 -9
\n" ); document.write( " 6 y = 6
\n" ); document.write( " y = 1
\n" ); document.write( " \n" ); document.write( "

\n" );
