Question

find the sum of 6 a + 8 b -7c,2b+c-4a and a-3b-2c

Answer 1

Given: Three terms 6a + 8b - 7c, 2b + c - 4a and a - 3b - 2c

To find: The sum of the three terms.

Solution:

• Now we have given three terms:

                 6a + 8b - 7c, 2b + c - 4a and a - 3b - 2c

• Adding them, we get:

                 6a + 8b - 7c + 2b + c - 4a + a - 3b - 2c

                 a(6 - 4 + 1) + b(8 + 2 - 3) + c(-7 + 1 - 2)

                 3a + 7b - 8c

Answer:

            So the sum of the given three terms is 3a + 7b - 8c.
