Answer by sdmmadam@yahoo.com(530)   (Show Source):
You can put this solution on YOUR website! 5t+1>3t-13 ----(1)
5t-3t > -13-1 (grouping like terms, changing sign while changing side)
2t > -14
t > -14/2 (division by a positive quantity does not alter the inequality
and so here greater than remains greater than)
That is t > -7
Answer: t > -7
7t+15>3t-13 ----(2)
7t-3t > -13-15 (grouping like terms, changing sign while changing side)
4t > -28
t> -28/4
(division by a positive quantity does not alter the inequality
and so here greater than remains greater than)
That is t > -7
Answer: t > -7
