Imagine that you will be given a grade out of 100.
Your overall grade will come from two assignments, but they are weighted differently. Assignment 1 is worth 30% and assignment 2 is worth 70%.
For assignment 1, you receive 64/100, but you have not been told the result of assignment 2. You are, however, told that your overall mark is 67/100.
What grade did you get for assignment 2?

What grade did you get for assignment 2?
-
(0.30 * 64%) + (0.70 * x) = 67%
Now just solve for the x, which would give you the grade on the second test.

its
30% of A1 and 70% of A2
thus
(0.3x64)+(0.7x"X")=67
thus 0.7x"X"=47.8
"X"=68.28
