Beatrice's Bank Acount

Andrew and Beatrice each have their own savings account. Beatrice’s account has $600 less than three times what Andrew’s account has. If Andrew had $300 more dollars, then he would have exactly half what is currently in Beatrice’s account. How much does Beatrice have?

Let me see.

This problem is more involved.

Let B = Beatrice

Let A = Andrew

B = 3A - 600
A + 300 = (1/2)(B)

Is this the correct system of equations to solve this problem?

You say?

Yes, those equations will work.  You can most easily eliminate B, hence get A, then work out B.

Check your answer fits the facts.

Thanks. I found out that my equations also lead to the right answer.
