    I am going to set x=bonds and y=cds

    equation one

    x+y=32000

    equation 2

    x=y+8000

    substitute equation 2 back into equation 1

    (y+8000) + y=32000

    2y+8000=32000

    2y=24000

    y=12000 (cds)

    now you can take this y value and plug it back into either equation you want

    x=12000+8000

    x=20000 (bonds)

    I think all you do is $32,000 / $8,000 which is $4,000.

    Meaning $4,000 will be invested in each investment, I may be wrong though.
