We solve by substitution method\r
\n" ); document.write( "\n" ); document.write( "-4 x + 1 y = -11 .............1
\n" ); document.write( "1 y = -11 + 4 x
\n" ); document.write( "/ 1 =
\n" ); document.write( " y = -11 + 4 x
\n" ); document.write( "-5 x + -2 y = 10 .....................2
\n" ); document.write( "Substitute y in (2)
\n" ); document.write( "-5 x + -2 ( -11 + 4 x ) = 10
\n" ); document.write( "-5 x + 22 + -8 x = 10
\n" ); document.write( "-5 x -8 x = -12
\n" ); document.write( "-13 x = -12
\n" ); document.write( "/ -13
\n" ); document.write( "x= 12/13
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "-4 x + 1 y = -11
\n" ); document.write( "-4 * 12/13 + 1 y = -11
\n" ); document.write( "-48/13 + 1 y = -11
\n" ); document.write( "1 y = -95/13
\n" ); document.write( "y= -95/13
