1)8x + 7y = 3.37
\n" ); document.write( "2)5x + 11y = 3.10\r
\n" ); document.write( "\n" ); document.write( "multiply 1) by 5 and 2) by 8\r
\n" ); document.write( "\n" ); document.write( "40x + 35y = 16.85
\n" ); document.write( "40x + 88y = 24.80
\n" ); document.write( "----------------------
\n" ); document.write( "0x - 53y = -7.95\r
\n" ); document.write( "\n" ); document.write( "therefore y = 0.15\r
\n" ); document.write( "\n" ); document.write( "Sub y = 0.15 in 1)\r
\n" ); document.write( "\n" ); document.write( "8x = 3.37 - 1.05\r
\n" ); document.write( "\n" ); document.write( "x = .29\r
\n" ); document.write( "\n" ); document.write( "Answer is Pen = 0.29$ and Pencil = 0.15$
\n" ); document.write( "
