2) a - (2b - 3c) = a -2b + 3c

4) - ( a - 2b + 3c) = -a + 2b - 3c

2) a - ( b - (c-d) ) = a - ( b - c + d ) = a - b + c - d

4) a - ( b + (c - (d-k) )) = a - (b + (c-d+k) ) = a - ( b + c - d + k) = a - b - c + d - k

2) 5x - (2y - 3x) = 5x - 2y + 3x = 8x - 2y

4) 4a + (2a - (3a+3) ) = 4a + ( 2a - 3a - 3) = 4a + 2a - 3a - 3 = 3a - 3
