Answer:
[tex]a=\frac{3(B-9)}{q}[/tex]
Step-by-step explanation:
Step 1: Write equation
[tex]B=9+\frac{1}{3} qa[/tex]
Step 2: Solve for a
- Subtract 9 on both sides: [tex]B-9=\frac{1}{3} qa[/tex]
- Multiply 3 on both sides: [tex]3(B-9)=qa[/tex]
- Divide both sides by q: [tex]\frac{3(B-9)}{q} =a[/tex]
- Rewrite: [tex]a=\frac{3(B-9)}{q}[/tex]
