Question

subtract sum of 2a+b,-3a+b,-2a-2b from -6a+3b​

Answer 1

Answer:

$(2a + b) + ( - 3a + b) + ( - 2a - 2b) \\ = \cancel{2a} \cancel{+ b} - 3a \cancel{+ b} \cancel{ - 2a} \cancel{ - 2b} \\ = \underline{ \underline{ - 3a}} \\ \\ (- 6a + 3b) - ( - 3a) \\ = - 6a + 3b + 3a \\ = \underline{ \underline{ - 3a + 3b}}$
