Simplifying
Y + 2 = y
Reorder the terms:
2 + Y = y
Solving
2 + Y = y
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + Y = -2 + y
Combine like terms: 2 + -2 = 0
0 + Y = -2 + y
Y = -2 + y
Simplifying
Y = -2 + y
I know that solution but it doesn't work when the 'y' terms are both lower case. Only works for one 'y' and one 'Y' as in Y + 2 = y. So your answer is wrong. The problem given is y+2 = y
