Algebra.Com's Answer #20866 by MrTillman(3)![]() ![]() ![]() You can put this solution on YOUR website! First get the variable, d, on one side of equation like this:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "14 -d + d = -7 + 6d + d (since d is negative on left side you have to add +d to take it away, and you add it to the other side)\r \n" ); document.write( "\n" ); document.write( "Now you have 14 = -7 + 6d + d add the d's to get 14 = -7 + 7d\r \n" ); document.write( "\n" ); document.write( "Now you have to get the d term by itself, like above you simply get rid of the negative 7 by moving it to the other side with the 14. \r \n" ); document.write( "\n" ); document.write( "14 = -7 + 7d \n" ); document.write( "14 + 7 = -7 + 7 + 7d (again, since it is a negative 7, you have to add +7 to it in order to take it away, but also add it to other side to the 14\r \n" ); document.write( "\n" ); document.write( "Now you have 14 + 7 = -7 + 7 + 7d Combine the numbers by itself to get \r \n" ); document.write( "\n" ); document.write( "21 = 7d\r \n" ); document.write( "\n" ); document.write( "Now solve for d by dividing both sides by 7\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "d = 3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
