I solved the right hand equation but had to reject the left hand side equation since i could not logarithm a negative number. So do i reject the whole solution or just write the right hand side equation solution?

Why not simplify the stuff in the modulus first?

Left hand side:

Right hand side:

(REJECT)

I rejected the right hand solution because I can't logarithm a negative number. So do I have to reject the left hand side solution too? Since in

and , and means they come together, since i cant find a solution for one of the parts, i should reject the whole solution, am i right?
