multiply by 7, isolate the A term, and use the distributive property
7B=3A-33
7B + 33 = 3A
divide by 3
7B/3 +11 = A

Step 1: Distribute the 3/7
3/7(A-11) = 3/7A- 11(3/7) = 3/7A-33/7
so you have B = 3/7A - 33/7
Step 2: Isolate A
3/7A-33/7 + 33/7 = B + 33/7
3/7A = B+33/7
Step 3: Divide both sides by 3/7 to get A alone
A = (B + 33/7) / 3/7
A = B + 33/7 * 7 /3 (divisionof fractions= invert then multiply)
A = (7B +33) / 3
A = 7B/3 + 33/3 = 7B/3 + 11
Final Answer: 7B/3 +11
