Yes, Dale, these problems often seem to have funny English...
Look at the second sentence:
If the second of the two forces is 6.4 N more than the first and the third is four times the first, what are the forces?
To illustrate what this means, let me just take a guess value for the first force.
Force 1: 10 N (this is my guess value)
Force 2: 16.4 N (this is because it says the second force has to be 6.4 N more than the first)
Force 3: 40 N (this is because the third force has to be four times the first).
[Note: My guess of 10 N for the first force is not the right answer, because the first condition fails ("the sum of two forces must equal the third force") since 10 + 16.4 ≠ 40.]
It may have been easier if the question said:
"The second of the two forces is 6.4 N more than the first. The third force is four times the first. What are the forces?"
