Algebra.Com's Answer #70237 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! let the number be a, so:\r \n" ); document.write( "\n" ); document.write( "Twelve less than 2 times a number is equal to 15 minus 7 times the number \n" ); document.write( "12 less than 2a = 15 - 7a\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so, 12 less than 2a: \n" ); document.write( "what is 12 less than 20? answer is found by 20-12 \n" ); document.write( "what is 12 less than 30? answer is found by 30-12 \n" ); document.write( "so, what is 12 less than 2a? answer is found by 2a-12\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so, 2a-12 = 15-7a is the equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2a-12 = 15-7a --> add 7a to both sides \n" ); document.write( "9a-12 = 15 --> add 12 to both sides \n" ); document.write( "9a = 27 \n" ); document.write( "a = 27/9 \n" ); document.write( "a = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "cheers \n" ); document.write( "jon \n" ); document.write( " \n" ); document.write( " |
