Translate to a system of equations: daniela invested a total of $50,000, some in a certificate of deposit (cd) and the remainder in bonds. the amount invested in bonds was $5,000 more than twice the amount she put into the cd. how much did she invest in each account? call the amount that daniela invested in the cd d and the amount she invested in bonds b.

Daniela invested $35,000 in bonds and $15,000 in a certificate of deposit (CD)

The first conditions of the problem is the total amount invested is $50,000, so

The second demands that the amount invested in bonds was $5,000 more than twice the amount she put into the CD

a)

The system of equations is

b) To solve the system, we take b from the last equation and replace it in the first equation:

Rearranging

Solving

And  

Daniela invested $35,000 in bonds and $15,000 in a certificate of deposit (CD)

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

i think its a and d
