Answer:
![\boxed{\bold{3+4x](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cbold%7B3%2B4x%3C2%281%2B2x%29%7D%7D)
Step-by-step explanation:
Expand ![\bold{2\left(1+2x\right): \ 2+4x}](https://tex.z-dn.net/?f=%5Cbold%7B2%5Cleft%281%2B2x%5Cright%29%3A%20%5C%202%2B4x%7D)
![\bold{3+4x](https://tex.z-dn.net/?f=%5Cbold%7B3%2B4x%3C2%2B4x%7D)
Subtract 3 from both sides
![\bold{3+4x-3](https://tex.z-dn.net/?f=%5Cbold%7B3%2B4x-3%3C2%2B4x-3%7D)
Simplify
![4x](https://tex.z-dn.net/?f=4x%3C4x-1)
Subtract 4x from both sides
![\bold{4x-4x](https://tex.z-dn.net/?f=%5Cbold%7B4x-4x%3C4x-1-4x%7D)
Simplify
0 < -1
