A sketch of the propblem would be great. Does this forum allow sketches?

A simple approach is to name the values to match the column. If C12 is the value in column C, row 12, , then let v = C12 Similarly, let d = C8. Now prepare the equation using those values directly. Check each component and the first answer .

Sketches of this problem and solution would be helpful.
