4(r-7)+2>5(r+3)-28
4r - 28 > 5r + 15 - 28
-r > 15
r < -15
I think Reiny lost the +2 on the left...

4r-28+2>5r+15-28
-r>13
r<-13
I missed the +2
Let's try again

4(r-7)+2>5(r+3)-28
4r - 28 + 2 > 5r + 15 - 28
-r > 15 - 2
r < -13
thank you so much... I tend to make things too difficult I don;t know why I do this.. and the extra number and letters throw me off... thank you I will use this tip for further references... appreciate it so much
