Question

(A-B+3C) FROM (2C-A-3B)​

Answer 1

Answer:

-2A - 2B - C

Step-by-step explanation:

Subtracting (A - B + 3C) from (2C - A - 3B) :

=> 2C - A - 3B - (A - B + 3C)

=> 2C - A - 3B - A + B - 3C    (Minus and minus combine to become plus; minus and plus combine to minus)

=> -A - A -3B + B + 2C - 3C    (Combining like terms)

=> -2A - 2B - C is the answer.
