# Modulus Functions Help Watch

1. Need help with this question - 9 - |2x-6| = 4
I tried to work out by solving for x and then subtracting 9 but clearly thats wrong, so how do I do it?

Is there even any solutions for this? I can't find any

I presume you mean 9 - |2x - 6| rather than negative 9.

I can't really see what you tried to do? Take the modulus to one side and the rest to the other, and it should be fine to do after that.

Do you mean

9 - |2x - 6| = 4

?

Just add |2x - 6| to both sides and subtract 4 from both sides. Then solve.
