2t+7 is less than t+15
Subtracting t from both sides
2t+7-t is less than t+15 - t
t+7 is less than 15
Subtracting fm 7 from both sides
t+7-7 is less than 15-7
t is less than 8

Can you do it for this one?? Follow the same idea as above.Bring the terms containing t to one side and take the rest of the terms to the other side.
5t+6 is greater than or equal to 2t+12
