Question

7a-4b+12c-4b-5a-3b+2d-6c​

Answer 1

$7a - 4b + 12c - 4b - 5a - 3b + 2d - 6c = \\ 2a - 11b - 6c + 2d$

Answer 2

To simplify the given expression, let's group like terms together:

7a - 4b + 12c - 4b - 5a - 3b + 2d - 6c

Combining the like terms, we have:

(7a - 5a) + (-4b - 4b - 3b) + (12c - 6c) + 2d

Simplifying further:

2a + (-11b) + 6c + 2d

The simplified expression is:

2a - 11b + 6c + 2d
