Simplify 2a − 4b +7 + 8a + 6b − 2

To simplify the expression \(2a - 4b + 7 + 8a + 6b - 2\), we will combine like terms.

1. Combine the terms with \(a\):
\(2a + 8a = 10a\)

2. Combine the terms with \(b\):
\(-4b + 6b = 2b\)

3. Combine the constant terms:
\(7 - 2 = 5\)

Putting it all together, the simplified expression is:
\[
10a + 2b + 5
\]

So the correct response is:
**10a + 2b + 5**.
