6%282a-6%29%3E=4%284a%2B4%29 Start with the given inequality.


12a-36%3E=16a%2B16 Distribute.


12a%3E=16a%2B16%2B36 Add 36 to both sides.


12a-16a%3E=16%2B36 Subtract 16a from both sides.


-4a%3E=16%2B36 Combine like terms on the left side.


-4a%3E=52 Combine like terms on the right side.


a%3C=%2852%29%2F%28-4%29 Divide both sides by -4 to isolate a. note: Remember, the inequality sign flips when we divide both sides by a negative number.


a%3C=-13 Reduce.

Answer:

So the solution is a%3C=-13
