Please help me! Write down a way I found the answer or why it is correct for me please! I will give Brainiest. Worth 45 points! But please help me do it correctly!!

Y + 7 = 25
-7 -7
y = 18

explaination:
y + 7 is the original problem you are given, then it tells you that you are halfway up the ladder, so instead of y + 7 = 50 , it would be y + 7 = 25 (half of 50)
then, you have to get your variable (y) by itself on its side of the equal sign, so you would subtract 7 , but what is done to one side of the equal sign has to be done to the other, so you would subtract 7 from 25 aswell, leaving you with the problem y = 18

I hope this helped! please give brainiest!
