How can you make the following equation true by drawing only one straight line:

5+5+5=550

Can you figure it out?

We draw a line in the upper left corner in the first visible plus
sign from the left, transforming the "+" into a "4".

The equation thus becomes:
545 + 5 = 550,
which is indeed accurate as the rhs of the equation is equal to its lhs.
