-2x-9y= -25 .............1
\n" ); document.write( "-4x-9y =-23 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "2x+9y= 25
\n" ); document.write( "-4x-9y= -23
\n" ); document.write( "Add the two equations
\n" ); document.write( "-2x= 2
\n" ); document.write( "/ -2
\n" ); document.write( "x = -1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-2 x + -9 y = -25
\n" ); document.write( "2 + -9 y = -25
\n" ); document.write( " -9 y = -25-2
\n" ); document.write( " -9 y = -27
\n" ); document.write( " y = 3
