Answer 1

To simplify the expression 2a − 4b +7 + 8a + 6b − 2, you can combine like terms.

Combine the terms with a and the terms with b separately:

For the terms with a: 2a + 8a = 10a

For the terms with b: -4b + 6b = 2b

Combine the constant terms: 7 - 2 = 5

Therefore, the simplified expression is 10a + 2b + 5.
