13x+7y = 88 .............1
\n" ); document.write( "x+8y=-38 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -8
\n" ); document.write( "Multiply (2) by 7
\n" ); document.write( "-104x-56y=-704
\n" ); document.write( "7x+56y =-266
\n" ); document.write( "Add the two equations
\n" ); document.write( "-97x=-970
\n" ); document.write( "/-97
\n" ); document.write( "x=10
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "13 x + 7 y = 88
\n" ); document.write( "130 + 7 y = 88
\n" ); document.write( " 7 y = 88 -130
\n" ); document.write( " 7 y = -42
\n" ); document.write( " y = -6 \r
\n" ); document.write( "\n" ); document.write( "(10,-6)
\n" ); document.write( " \n" ); document.write( "
