Answer:
-5a - 4
Step-by-step explanation:
Since we can solve this equation fully, we can simplify the most we can.
First, add up the numbers.
7a - 8 - 12a + 4
-8 + 4 = -4
7a - 4 - 12a
Next, add up the terms. The term is the number that is combined with a variable such as in this case is "a"
7a - 4 - 12a
7a - 12a = -5a
-5a - 4 is equivalent to the expression of 7a - 8 - 12a + 4.
