To maintain density when changing SID, the radiographer can use which law or rule to change technique?

An exposure of 85 kVp and 200 mAs produces a correct density but too much contrast. What mAs should be used if the kVp is raised to 100 kVp?

If 5 mAs at 60 kVp produces an acceptable radiograph of the elbow. What new kVp would be needed to maintain density if the mAs was reduced to 2.5?
