you put 25 on the other side of the equal sign and it becomes -y = 12 - 25
and solve for y (you have make y positive)
25 —y =12

I do not understand
add y to both sides
25 - y + y = 12 + y
which is just 25 = 12+y
Now subtract 12 from both sides
25-12 = 12+y-12
which is just 13 = y
done!
If two things are equal, then if you change each the same way, they stay equal.
25 - y + y = 12 + y
which is just 25 = 12+y
Now subtract 12 from both sides
25-12 = 12+y-12
which is just 13 = y
done!
