<span>3c - 2cd - 8c + 7d
= -5c </span> - 2cd + 7d
hope it helps
That is sudoku, a game that I am really good at. first off the square on the left in the middle is messed up, because on the square above it there is a 5 where it would make the 5 in the middle left square incorrect. So you have to erase the 5 in the square on the middle left. Then if you can do sudoku, you could do the rest.
hope I helped!
The least common multiple would be 209
