To solve for a, you need to get the variable a by itself on one side of the equation. So, on eway to do this is to first subtract 2b from each side and get 9a=c+4a-2b. Then subtract 4a from both sides to get 5a=c-2b, and finally divide the entire equation by 5 and get a=1/5c-2/5b. I hope this helps.
