Answer with Step-by-step explanation:
1. x-7>10
Adding 7 on both sides,we get
x>17
2. 3x ≤ 21
Dividing both sides by 3,we get
x≤7
3. 5a-2<18
Adding 2 on both sides, we get
5a<20
Dividing both sides by 5,we get
a<4
4. 2t + 8 ≥ -4(t+1)
Distributing -4 on right hand side of inequality
2t+8 ≥ -4t-4
2t+4t ≥ -4-8
6t ≥ -12
Dividing both sides by 6, we get
t ≥ -2
