1. y-1>-17

In order to "undo" the -1, you need to add +1 to each side:
y-1+1>-17+1
y>-16

Now, the answer is given in what is called "set builder" notation, which is this:
{y|y>-16}

Translated into English: "the set" "of all values of y" "such that" "y>-16".

"{"="set"
"y"="of all values of y"
"|" the vertical line means "such that"

2. d=2e , to get rid of the 2, which is multiplied by the "e", you have to "undo" it by DIVIDING both sides by 2:
d=2e
d%2F2=%282e%29%2F2
d%2F2=e
