1 x -6 y = -7 .............1
\n" ); document.write( "9 x -8 y = -17 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 8
\n" ); document.write( "Multiply (2) by -6
\n" ); document.write( "8 x -48 y = -56
\n" ); document.write( "-54 x 48 y = 102
\n" ); document.write( "Add the two equations
\n" ); document.write( "-46 x = 46
\n" ); document.write( "/ -46
\n" ); document.write( "x = -1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + -6 y = -7
\n" ); document.write( "-1 + -6 y = -7
\n" ); document.write( " -6 y = -7 + 1
\n" ); document.write( " -6 y = -6
\n" ); document.write( " y = 1 \n" ); document.write( "
