The following equation is made of 10 matches:
L + L = L (more than 1 solutions)

The following equation is made of 12 matches:
VI = IV - III (more than 1 solutions)

The following equation is made of 14 matches:
XIV - V = XX

The following equation is made of 11 matches:
IX - IX = V

The following equation is made of 12 matches:
