Algebra.Com's Answer #504864 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! Multiply both sides by 2, because fractions are annoying. You can also subtract (3/2)d from both sides to get (1/2)d = 9 --> d = 18, which is also a perfectly valid solution. \n" ); document.write( " |
