You can put this solution on YOUR website!
2 x + 3 y = 29 .............1
\n" ); document.write( "-4 x + 5 y = 19 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-10 x -15 y = -145
\n" ); document.write( "-12 x 15 y = 57
\n" ); document.write( "Add the two equations
\n" ); document.write( "-22 x = -88
\n" ); document.write( "/ -22
\n" ); document.write( "x = 4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 3 y = 29
\n" ); document.write( "8 + 3 y = 29
\n" ); document.write( " 3 y = 29 -8
\n" ); document.write( " 3 y = 21
\n" ); document.write( " y = 7
\n" ); document.write( " \n" ); document.write( "

\n" );
