Answer 1

[AI-generated answer — Bot GPT 3.5]

To simplify the expression, we first distribute the negative sign into the second parentheses:

(7.8x + 8.7) - (-4.34x + 3.16) = 7.8x + 8.7 + 4.34x - 3.16.

Now we can combine like terms:
(7.8x + 4.34x) + (8.7 - 3.16) = 12.14x + 5.54.

So the simplified expression is 12.14x + 5.54.
