What do you think the answer is? I wish I could give it to you, but it is against the rules.

Pretend her brother is 16, and she is 10. What is 16+10? 26.
Put 16 in place for "b" and solve each equation. Whichever one comes out to be 26 is your answer. I hope this isn't too confusing!

Wow thanks! Well I got 10 for a and c and d is a repeating decimal but b is 26 so I'm guessing  2B-6 is the correct answer
