You can put this solution on YOUR website!
3 x + 2 y = 13 .............1
\n" ); document.write( "2 x -1 y = 4 .............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 2 y = 13
\n" ); document.write( "4 x -2 y = 8
\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 + 2 y = 13
\n" ); document.write( "9 + 2 y = 13
\n" ); document.write( " 2 y = 13 -9
\n" ); document.write( " 2 y = 4
\n" ); document.write( " y = 2 \r
\n" ); document.write( "\n" ); document.write( "(3,2) is the solution
