X=lbs of hamburger that costs$1.60
\n" ); document.write( "70=lbs of hamburger that costs $2.10\r
\n" ); document.write( "\n" ); document.write( "Even thought the cost varies the total quantity of meat is constant.\r
\n" ); document.write( "\n" ); document.write( "1.60x+(2.10)(70)=1.70(x+70)\r
\n" ); document.write( "\n" ); document.write( "1.60x+147=1.70x+119\r
\n" ); document.write( "\n" ); document.write( "Subtract 1.60x from both sides \r
\n" ); document.write( "\n" ); document.write( "subtract 119 from both sides
\n" ); document.write( "28=.1x\r
\n" ); document.write( "\n" ); document.write( "divide both sides by .1\r
\n" ); document.write( "\n" ); document.write( "280=x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let's doublecheck our answer by replacing the x with 280\r
\n" ); document.write( "\n" ); document.write( "1.6(280)+147=(350)1.7\r
\n" ); document.write( "\n" ); document.write( "448+147=595\r
\n" ); document.write( "\n" ); document.write( "595=595
\n" ); document.write( "
