Algebra.Com's Answer #268183 by robertb(5830)![]() ![]() You can put this solution on YOUR website! x = cost of one book, y = cost of another book. Then x = y + 5, and x+y = 19. Then y+5 + y = 19, or 2y + 5 = 19, or 2y = 14, or y = $7, the cost of the other book. The first book costs x = $12. \n" ); document.write( " |
