a sweater cost $12 more than a shirt. Together they cost $46. What was the price of the shirt?\r
\n" ); document.write( "\n" ); document.write( "Sweater + Shirt = 46
\n" ); document.write( "Sweater = Shirt + 12
\n" ); document.write( "So, (Shirt+12) + Shirt = 46
\n" ); document.write( "2Shirt + 12=46 [Solve for the \"Shirt\"]
\n" ); document.write( "2Shirt=46-12
\n" ); document.write( "2Shirt=34
\n" ); document.write( "2/2Shirt=34/2
\n" ); document.write( "Shirt=$17
\n" ); document.write( "or
\n" ); document.write( "x+y=46
\n" ); document.write( "(y+12)+y=46
\n" ); document.write( "2y+12=46
\n" ); document.write( "2y=46-12
\n" ); document.write( "2y=34
\n" ); document.write( "2/2y=34/2
\n" ); document.write( "y=17
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "Check by plugging the values back into the original equation:
\n" ); document.write( "Sweater + Shirt = 46
\n" ); document.write( "(17+12) + 17=46
\n" ); document.write( "29+17=46
\n" ); document.write( "46=46 [checks out]
\n" ); document.write( " \n" ); document.write( "
\n" );
