You can put this solution on YOUR website!
y = x-4
\n" ); document.write( "2 x + -5 y = 2
\n" ); document.write( "Substitute y in the second equation
\n" ); document.write( "2 x + -5 (x-4) = 2
\n" ); document.write( "2 x -5x+20 = 2
\n" ); document.write( "2 x -5 x = -18
\n" ); document.write( "-3 x = -18
\n" ); document.write( "/ -3
\n" ); document.write( "x= 6
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "-1 x + 1 y = -4
\n" ); document.write( "-1 * 6 + 1 y = -4
\n" ); document.write( "-6 + 1 y = -4\r
\n" ); document.write( "\n" ); document.write( "y=6-4
\n" ); document.write( "y = 2
\n" ); document.write( "
