If the values are over-constrained, ignore the value for 'left' (in case the 'direction' property of the containing block is 'rtl') or 'right' (in case 'direction' is 'ltr') and solve for that value.

10.3.7 Absolutely positioned, non-replaced elements
So:
20% : left
+
0px : margin-left
+
0px : border-left-width
+
0px : padding-left
+
20% : width
+
0px : padding-right
+
0px : border-right-width
+
0px : margin-right
+
20% : right
====================
500px : width of containing block (width of Initial Containing Block)
becomes
ignore and solve : left
+
0px : margin-left
+
0px : border-left-width
+
0px : padding-left
+
100px : width (20% of 500px == 100px)
+
0px : padding-right
+
0px : border-right-width
+
0px : margin-right
+
100px : right
====================
500px : width of containing block (width of Initial Containing Block)
so used left offset value must be 300px .
