The amount invested in A bonds at 10% yield is x; the amount invested in AAA bonds at 6% yield is 2x; the rest, $50,000-3x, is invested in AA bonds at 7% yield.

The total income from the investments is $3620.

.10%28x%29%2B.06%282x%29%2B.07%2850000-3x%29+=+3620

You can solve that with simple algebra....
