Answer:
a=1
4+3a+8<16
2a+3<9-3a
5a-4a+6<8
a=2
2a+3>10-3a
3a-2a+1>2
14+5a<12a+1
Explanation:
To figure out the answer multiply the value of 'a' by the number next to it. For example, let's try the first equation. For 4+3a+8<16, you'd substitute 'a' with 1, making it 4+3(1)+8<16. Then you'd use the order of operations (PEMDAS) to solve the rest of it.
