2a-4b+7+8a+6b-2

Combining like terms, we have:

(2a + 8a) + (-4b + 6b) + (7 - 2)

This simplifies to:
10a + 2b + 5

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

Step 1: Combine the terms with 'a':
2a + 8a = 10a

Step 2: Combine the terms with 'b':
-4b + 6b = 2b

Step 3: Combine the constant terms:
7 - 2 = 5

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

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

First, let's group the terms with the same variables together:
(2a + 8a) + (-4b + 6b) + (7 - 2)

Next, we add or subtract the coefficients of the grouped terms:
10a + 2b + 5

So the simplified expression is 10a + 2b + 5.
