Algebra.Com's Answer #532748 by KMST(5328)![]() ![]() You can put this solution on YOUR website! NOTE 1: I will try to show the work baby step by baby step. \n" ); document.write( "It may be way too babyish for the level you are at, \n" ); document.write( "so feel free to skip baby steps you do not need. \n" ); document.write( " \n" ); document.write( "NOTE 2: You are more likely to get help and for that help to be answers to the right questions \n" ); document.write( "if you use a way to write math that communicates what you mean more clearly. \n" ); document.write( "I will be guessing what you mean a lot, so if I did not guess right, ask again, in a clearer way. \n" ); document.write( "Here are some commonly used symbols: \n" ); document.write( "* is the times sign, as in writing 3*5 for 3 times 5. \n" ); document.write( "/ is the \"over\" or dividing symbol as in 35/7=5 for 35 divided by 7 equals 5, or \n" ); document.write( "x/(7-x) for \n" ); document.write( "When writing with pen and paper, that horizontal line meaning \"over\" is a great ink-saver. \n" ); document.write( "In the conventional algebra language, \n" ); document.write( "that horizontal line means that the expressions above and below the line are calculated first, before dividing, \n" ); document.write( "and you do not need to write the parentheses. \n" ); document.write( "When typing, if there is an expression above (or below) that horizontal line that you read as \"over\", \n" ); document.write( "you have to wrap that expression in parentheses. \n" ); document.write( "Examples: \n" ); document.write( "x/(7-x) means \n" ); document.write( "Also, according to the conventions (rules) on \"order of operations\", \n" ); document.write( "(x+2x)/6 - 3 = \n" ); document.write( "\n" ); document.write( "1.
