Step-by-step explanation:

If you notice the numbers before the variables are the same as in the answer. Therefore, all we need to know is about the placement in the number system.

So a has to be 10, b has to be 1, c has to be 0.1 d 0.01 and e 0.001.

You can now very easily find the value of 5a + 4c + 7e.

It will 50 + 0.4 + 0.007 = 50.407
