This is a matter of converting English into algebra, so let's look at it word by word.\r \n" ); document.write( "\n" ); document.write( "\"Latoya\" - let's create the variable L to stand for Latoya's age \n" ); document.write( "\"is\" - means \"=\" \n" ); document.write( "\"twice as old as\" means we will be multiplying by 2. \n" ); document.write( "\"her cousin\" - we need a new variable C to represent her cousin's age \n" ); document.write( "\"was three years ago\" - 3 years ago means we will have to subtract 3\r \n" ); document.write( "\n" ); document.write( "So our first sentence boils down to \"Latoya (L) is (=) twice as old as (2 times) her cousin (C) three years ago (-3)\" or: \n" ); document.write( " \n" ); document.write( "The second part says: \n" ); document.write( "\"The sum of\" - means we'll be adding together \n" ); document.write( "\"their ages now\" - L & C \n" ); document.write( "\"is\" - still means equals \n" ); document.write( "\"15\" - 15 \n" ); document.write( "This translates to: \n" ); document.write( " \n" ); document.write( "Now you have two equations, that you can solve either through elimination, substitution, graphing, or any other way you've been taught to solve for the ages of each L & C. \n" ); document.write( " |
