Algebra.Com's Answer #364585 by jlshires(17) ![]() You can put this solution on YOUR website! Remember PEMDAS- it's the order in which you do things in a problem:\r \n" ); document.write( "\n" ); document.write( "Parentheses \n" ); document.write( "Exponents \n" ); document.write( "Multiply \n" ); document.write( "Divide \n" ); document.write( "Addition \n" ); document.write( "Subtraction\r \n" ); document.write( "\n" ); document.write( "In this case, since you have variables, you can't do what's in the parentheses first (n-5) so start with the multiplication.\r \n" ); document.write( "\n" ); document.write( "Multiply 2 out to everything in the parentheses ( 2(n-5) is really 2(n)-2(5))\r \n" ); document.write( "\n" ); document.write( "2(n-5)+n \n" ); document.write( "2(n)-2(5)+n \n" ); document.write( "2n-10+n\r \n" ); document.write( "\n" ); document.write( "combine all the like statements (2n+n)\r \n" ); document.write( "\n" ); document.write( "the final answer is 3n-10 \n" ); document.write( " |
