Please help me!:) and show the steps if you can!<3​

Answer 1

2a + 4b

Explanation:

Its not hard, you just need to add all the numbers with the same variable together, such as 3b and b. They stay in the same place as the first one with the variable is at. a + a would not make it 1a it would be 2a because there are 2 A's.
