1. n + 1 > -2

2. t over -1 > -2

3. -4k -1 = 47

What is the question you are trying to ask? Provide more information.

1) n + 1 > -2
 Subtract 1 from the both sides, 
 n + 1 - 1 > -2 - 1
 n > -3

2) T/-1 > -2
 Multiply both sides by -1, 
  T/-1 * -1 < -2*-1   [ sign changed 'cause multiplied by -1 ]
 T < 2

3) -4k - 1 = 47
Add 1 to the both sides, 
 -4k - 1 + 1 = 47 + 1
 -4k = 48
 Divide -4 from both sides, 
 -4k/-4 = 48/-4
 k = -12
