Algebra.Com's Answer #322898 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! I assume that problem is: \n" ); document.write( "14(.3n - .31) = 5.18 - (.4 - 4.22n) \n" ); document.write( ": \n" ); document.write( "Multiply what is inside the brackets on the left side, results \n" ); document.write( "4.2n - 4.34 = 5.18 - (.4 - 4.22n) \n" ); document.write( ": \n" ); document.write( "remove the brackets, a neg outside the brackets changes the signs inside, results \n" ); document.write( "4.2n - 4.34 = 5.18 - .4 + 4.22n \n" ); document.write( "4.2n - 4.34 = 4.78 + 4.22n \n" ); document.write( ": \n" ); document.write( "Group the n's on the left and the numbers on the right and you have \n" ); document.write( "4.2n - 4.22n = 4.78 + 4.34 \n" ); document.write( "-.02n = 9.12 \n" ); document.write( ": \n" ); document.write( "Make n positive and get rid of the decimals, Multiply both sides by -100 \n" ); document.write( "2n = -912 \n" ); document.write( ": \n" ); document.write( "Divide both sides by 2 \n" ); document.write( "n = \n" ); document.write( "n = -456 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Let's see if that flies in the original equation \n" ); document.write( "14(.3n - .31) = 5.18 - (.4 - 4.22n) \n" ); document.write( "replace n with -456 \n" ); document.write( "14(.3(-456) - .31) = 5.18 - (.4 - 4.22(-456)) \n" ); document.write( "14(-136.8 - .31) = 5.18 - (.4 + 1924.32) \n" ); document.write( "14(-137.11) = 5.18 - 1924.72 \n" ); document.write( "-1919.54 = -1919.54, confirms our solution of n =-456 \n" ); document.write( " \n" ); document.write( " |
