You can put this solution on YOUR website!
Start by rearranging equations
\n" ); document.write( "3x + 2y = 5 ....1
\n" ); document.write( "2x - 3y = 12....2
\n" ); document.write( "Multiply (1) by 3
\n" ); document.write( "and (2) by 2
\n" ); document.write( "9x + 6y = 15.....3
\n" ); document.write( "4x - 6y = 24.....4
\n" ); document.write( "Add (3) + (4)
\n" ); document.write( "13x = 39
\n" ); document.write( " x = 3
\n" ); document.write( "Substitute x = 3 in (1)
\n" ); document.write( "3(3) + 2y = 5
\n" ); document.write( " 9 + 2y = 5
\n" ); document.write( " 2y = 5 - 9
\n" ); document.write( " 2y = -4
\n" ); document.write( " y = -2
\n" ); document.write( "x = 3: y = -2
\n" ); document.write( "Hope this helps
