To solve the equation $8 = 3a - 4$:

1. Add 4 to both sides to isolate the term with $a$: $8 + 4 = 3a - 4 + 4$ $12 = 3a$

2. Divide both sides by 3 to solve for $a$: $\frac{12}{3} = \frac{3a}{3}$ $a = 4$

So, the solution is $a = 4$.

Here are 5 related questions to further your understanding:

1. What happens if you subtract 4 instead of adding 4 at the beginning?
2. How would the solution change if the equation was $8 = 3a + 4$?
3. Can you solve $8 = 4a - 6$?
4. What are the steps to check if your solution is correct?
5. How would you approach solving $3a - 4 = 2a + 3$?

Tip: Always perform the same operation on both sides of an equation to maintain equality!
