Answer:
A=11
Step-by-step explanation:
You have to combine similar terms on both sides of the equation. 9a -7a equal 2a. On the other side you will do 3a+2a which equals 5a then you’ll leave -33 by itself.
2a=5a-33
You must subtract 5a from both sides of the equation which leaves you with; -3a=-33. Finally you divide both sides by -3. Which leaves you with your final answer a=11
