First you need to put **the conditions**:

x > 0*for log*

4-x ? 0*for first radical* => x ? 4

2x-1 > 0* for the sec radical* => x

So, we get

x ∈ (1/2;4]

And now, the equations become:

But here we have to consider k = 0 and we have

x = 1 ∈ (1/2;4]

So 1 is a good solution

x > 0

4-x ? 0

2x-1 > 0

So, we get

x ∈ (1/2;4]

And now, the equations become:

But here we have to consider k = 0 and we have

x = 1 ∈ (1/2;4]

So 1 is a good solution
