Solve each problem by using a system of three equations inthree unknowns.
Paranoia. Fearful of a bank failure, Norman split his life savings of 60,000 dollars among three banks. He received 5 \%,6 \%, and 7 \% on the three deposits. In the account earning 7 \% interest, he deposited twice as much as in the account earning 5 \% interest. If his total earnings were 3760 dollars, then how much did he deposit in each account?

guy with three bank accounts. You called him X, Y and Z. You know, the total amount invests these bank accounts equals $60,000. You know the return he gets from each of them get 0.5 in the 1st 1 You know, six from the 2nd 1 and point those seven from the third walk. You know, his total return is 3760. Finally, we know the amount invested in the third equals two times The amount invests in the first. So now we solved here. We have Z equals two acts. Um, so we have bad in terms of X. Now I have to get why, in terms of acts, why equals 60,000 minus Z, which we noticed. Two acts minus X B minus reacts. So now we have 20.5 problems, X plus point of six times 60,000 my reacts plus point of seven. I'm two X is gonna equal 3760. We'll solve this us What? 06 times 60,000 is 3600 minus on a 20 thanks, plus 0.14 acts because +37 its well appointed five x 0.14 Accident minus point 18 x That's 180.1 acts equals 160. So now the axe is gonna equal 16,000. It's Z equals 32,000. Misuse of why equals 60,000 minus 40,000. 12 1000 right?
