Here's two of them for you:

5 + 5 + 5 = 550

Add just one match/line/stroke to make the equation true.


7 + 1 = 5 - 1

Move one symbol/number/sign to make this equation true.

Always a good idea with these types of problems. However, that's not the best answer. Let's say you want to make the two sides of the equations equal to each other rather than just make the equations true.

As far as the second one is concerned, you have to move one whole sign (or number/character/whatever) and only one.

for the second one, take the 7, flip it upside down, put it on top of the 1

then it reads +4 = 5 - 1
