You probably need to use the Triangle Inequality. . So that means . And since that means . Can you go from here?
yeah, cheers !
I was doing a similar question. What is the solution set of mod(2x+5) <= mod(x+1) ? I think it is {x: x=-2, x=4}. The question actually asks for the interval and gives the answer [-4,-2].
The answer is correct. Both sides of the equation can be squared to find the soloution. I have done it now.
