7. II x XIV = XXVI + II (2 x 14 = 26 + 2)

II x IX = XVI + II (2 x 9 = 16 + 2)




Couldn't #1 just simply be II x II = IV?

Jema, you show two equations but you rearranged the numerals. This puzzle requires you to subtract one line from each side of the equation.

And yes, your #1 would work if you removed two lines from each side.

OK. I misunderstood what "Remove one line segment from each side of the equal sign ..." meant.

How about

7. II x XII = XXII + II (2 x 12 = 22 + 2)?
On each side of = the V becomes I.

10. III x XXIX = XL + XLVII
II x XXIX = XI + XLVII

6. II x XXXI = XLV + XVII

I x XXXI = XIV + XVII : 1 * 31 = 14 + 17

Excellent solves all!
