-2t + 5 > -7

you subtract 5 from each side

-2t + 5 > -7

    - 5    - 5

 -2t  >   - 12    then, you divide both side by -2 so you can get t                        by it's self.      

  -2       -2

                          When you divide a number by a number that is negative you flip  your greater than or less than sign.

so,  the answer is t < 6 or  A
