    \[\left| x-1 \right|=7 \Rightarrow x-1 = ???\] what does x-1 have to be? (Hint: it can be more than one value)

    think of it like this...\[\left| \,\,\,\,\,\, \right|=7\]what values can be inside?

    yeah, the equation you gave in the question doesn't match any of the responses... check your equation and write it correctly, please

    well, similarly: if \[\left| \,\,\,\, \right|>7\]what values are possible inside? do you understand absolute values?

    If \[|x-1|>7\] \[\implies(x-1)>7\implies x>8 \ \ \ \ \ \ \ \ \ ......\mathrm{mark\ this}\] or\[\implies (x-1)<-7 \implies x<-6\ \ \ \ \ \ \ \ \ \ \ \ \ ...... \mathrm{and\ this}\] Hence option B is right!

    absolute values are they same as distance... you're never a negative distance away from anything, only different directions. i'm in san diego and la is about 100 miles north.... ensenada (a town in mexico) is about 100 miles south. they are the same distance but different directions. it's the same with numbers. 7 is 7 away from 0. -7 is also 7 away from 0. so 7 and -7 are the same distance away from 0, but in different directions. so when the equation |x-1|>7 it's asking what values are more than 7 away from x-1. this implies that x-1 > 7 or x-1 < -7 because what ever is inside the absolute value signs has to be more than 7 (more than 7 miles north) or less than -7 (more than 7 miles south). make sense?
