SIMPLIFY THE FOLLOWING EXPRESSION *

22a + 12b

Step-by-step explanation:

First, you should combine like terms. Like terms are when numbers have the same variable, such as the variable 'a'.

26a and -4a both have 'a' as their variable. To combine them, add -4a to 26a. You should get 22a as your final result.

The other two numbers in this equation that share a common variable are 2b and 10b. To combine these, all you have to do is add them together. After adding these two, you should get 12b.

After combining all like terms, there is none left, meaning you can't combine 22a and 12b since they don't share the same variable.
