A is the concentration of the first container, B the second container.
300a+600b=900·(15)=13500
1.3a+6b=135
100a+500b=600·(12.5)=7500
2.a+5b=75
Multiply eq. 2 by (-3) and add to eq. 1 to eliminate A.
3a+6b-3a-15b=135-225
-9b=-90
b=10
Then from eq. 2,
a+50=75
a=25
The first container is a 25% solution and the second container is a 10% solution

Answer:
Step-by-step explanation:
hello :
f(t) = 1/t - 1
calculate : t
f(t)+1 = 1/t so : t = 1/(f(t)+1)
f^ -1 (t)= 1/(t+1)
