You can put this solution on YOUR website!
2d + 24 + 3d =84 (Solving for d, meaning get \"d\" completely alone)\r
\n" ); document.write( "\n" ); document.write( "First, combine like terms. d's and whole numbers.
\n" ); document.write( "2d+3d=5d\r
\n" ); document.write( "\n" ); document.write( "Second, Subtract 24 since it is on the wrong side and a positive number and take it to the 84. The 24 becomes negative because it was subtracted. Now you must subtract 24 from 84 which leaves you 60.
\n" ); document.write( "5d=60\r
\n" ); document.write( "\n" ); document.write( "Third, divide both sides by 5.
\n" ); document.write( "5d/5=60/5\r
\n" ); document.write( "\n" ); document.write( "d=12
\n" ); document.write( "Hope that helped.
