Question

2a + 6b + 8c, 16a + 13 b + 18c​

Answer 1

Answer:

2a + 6b + 8c, 16a + 13b + 18c = 18a + 19b + 26c.

Step-by-step explanation:

We add numbers which have the same variables, 2a + 16a = 18a, 6b + 13b = 19b, 8c + 18c = 26c. As we can't add different variables unless we know it's value, our answer comes down to 8c + 18c = 26c.
