\n" ); document.write( "3 x + 2 y = 78.85 .............1
\n" ); document.write( "2 x + 3 y = 74.8 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "-9 x -6 y = -236.55
\n" ); document.write( "4 x 6 y = 149.6
\n" ); document.write( "Add the two equations
\n" ); document.write( "-5 x = -86.95

\n" ); document.write( "x = 17
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 2 y = 78.85
