document.write( "Question 927445: A store sells tents, sleeping bags, and camp stools. A customer buys a tent, 3 sleeping bags, and 3 camp stools for $141. The price of the tent is 9 times the cost of a camp stool. The cost of a sleeping bag is $7 more than the cost of a camp stool. Find the cost of each item. \n" ); document.write( "

You can put this solution on YOUR website!
x = dollar cost of tent
\n" ); document.write( "y = dollar cost of bag
\n" ); document.write( "z = dollar cost of stool
\n" ); document.write( "---
\n" ); document.write( "x + 3y + 3z = 141
\n" ); document.write( "x = 9z
\n" ); document.write( "y = z + 7
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + 3y + 3z = 141
\n" ); document.write( "x - 9z = 0
\n" ); document.write( "y - z = 7
