Hello!\r \n" ); document.write( "\n" ); document.write( "Let's start by assigning our variable with a letter. I prefer n, but you can choose any letter (except the letter o).\r \n" ); document.write( "\n" ); document.write( "Taking the problem step by step, we have:\r \n" ); document.write( "\n" ); document.write( "12 times the number = 12n\r \n" ); document.write( "\n" ); document.write( "20 less than 12 times the number = 12n - 20\r \n" ); document.write( "\n" ); document.write( "Now, we equate the statement to 64:\r \n" ); document.write( "\n" ); document.write( "12n - 20 = 64 \n" ); document.write( "12n = 64 + 20 \n" ); document.write( "12n = 84 \n" ); document.write( "12n⁄12 = 84⁄12\r \n" ); document.write( "\n" ); document.write( "n = 7\r \n" ); document.write( "\n" ); document.write( "Therefore, we have our answer as 7.\r \n" ); document.write( "\n" ); document.write( "If you want to verify, you can multiply 7 by 12 (which is 84) and subtract 20 (which will give you 64).\r \n" ); document.write( "\n" ); document.write( "Hope this helped! x \n" ); document.write( " |
