Simplify 2c–3–5c + 7 + 9c–c

To simplify the expression (2c – 3 – 5c + 7 + 9c – c), follow these steps:

1. Combine like terms: Look for terms that involve (c) and constant terms.

– The (c) terms are: (2c – 5c + 9c – c).

– Combine these:

– (2c – 5c = -3c)

– (-3c + 9c = 6c)

– (6c – c = 5c)

2. Combine the constant terms: The constant terms are: (-3 + 7).

– Combine:

– (-3 + 7 = 4)

Putting it all together, the simplified expression is:

[5c + 4]

So the answer is 5c + 4. Great job on practicing simplification! If you have more questions, feel free to ask.
