Answer:
x=1
Step-by-step explanation:
-34x+6=-28
-6 -6
-34x=-34
-34 -34
x=1
Subtract 6 from both sides. on the left the 6 will be canceled out and on the right -28-6= -34
Than you divide -34 on both sides on the left the -34 will be canceled and on the right -34 divided bt-34 is positive 1. So x equals 1.

Answer:
9% fund: $
210,000
13% fund: $70,000
Step-by-step explanation:
As she wants to have a $28,000 annual return for her $280,000 investment, she is expecting a return rate of 10%:
![r=\dfrac{R}{C}=\dfrac{28,000}{280,000}=0.10](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7BR%7D%7BC%7D%3D%5Cdfrac%7B28%2C000%7D%7B280%2C000%7D%3D0.10)
If we call x the proportion of the capital in the 9% fund, then (1-x) is the proportion of the capital in the 13% fund,and the return of the combination has to be the expected return of 10%:
![0.09x+0.13(1-x)=0.10\\\\0.09x+0.13-0.13x=0.10\\\\-0.04x=0.10-0.13=-0.03\\\\x=\dfrac{0.03}{0.04}=0.75](https://tex.z-dn.net/?f=0.09x%2B0.13%281-x%29%3D0.10%5C%5C%5C%5C0.09x%2B0.13-0.13x%3D0.10%5C%5C%5C%5C-0.04x%3D0.10-0.13%3D-0.03%5C%5C%5C%5Cx%3D%5Cdfrac%7B0.03%7D%7B0.04%7D%3D0.75)
Then, we know that 75% of the capital should be invested in the 9% fund and 25% in the 13% fund.
This correspond to a capital of:
9% fund: 0.75*$280,000 = $
210,000
13% fund: 0.25*$280,000 = $70,000
