Find the sum in algebraic expression

Answer 1

Answer:

The answer is followed by:

Answer 2

The sum of the algebraic expressions is 4a - 6b + 27c

• Given expressions are

                       8a - 3b + 11c

                       5b - 6a + 7c

                       9c + 2a - 8b

• Sum of expressions

             = (8a - 3b + 11c) + (5b - 6a + 7c) + (9c + 2a - 8b)

             = (8a - 6a + 2a) + (- 3b + 5b - 8b) + (11c + 7c + 9c)

                                       [∵ grouping like terms]

             = (10a - 6a) + (5b - 11b) + (18c + 9c)

             = 4a - 6b + 27c
