Please help me use set builder notation to describe the complete solution of this:

39 - (3x+7) less than or equal to (x + 4) + x

equals x|x ?

Okay so what have you tried?

Can you solve

$39-(3x+7) \le (x+4)+x$

for x?

3. x is greater than or equal to 4. Is that right?

No I am sorry that is incorrect, but I don't know what error you made because you didn't show any work.
