Answer 1

I just took that quiz on k12. The answer is no solution. Hope I helped!

Answer 2

All real numbers.

Explanation:

To solve for x:

Simplify:
`4(x+1)\leq 4x+3`

Expand :
`4(x+1)=4x+4` we have,

`4x+4\leq 4x+3`

Subtract 4 from both the sides,

`4x+4-4\leq 4x+3-4`

Simplify we get,

`4x\leq 4x-1`

Subtract
`4x` from both the sides,

`4x-4x\leq 4x-1-4x`

On simplifying we get,

`0\leq -1`, which is false ∀ x∈
`R`
