Alright, let's break this down, starting with the left hand side (LHS), which is 2+2. As we know, 2+2 = 4.
Now for the right hand side (RHS):
2+2-6+2+7 = (2+2+2+7) - 6 = 6 + 7 - 6 = 7
But the RHS of the equation is not equal to the LHS, so the question is wrong (the equation as per the question is 4 = 7)
