Answer 1

your work was right, but check the values that you got, there might be an extraneous root.

Answer 2

your work was right, try plugging-in n = -3. on the original equation.

Answer 3

nope, you were right when you got n = -3. its just that, we check our it, to know if we consider it as a value for n, since we are dealing with absolute value, there cold be an extraneous roots.

Answer 4

before writing our answer, we must check the values that we got.

Answer 5

|-3-7| = 3(-3) - 1 can you tell me if we will get a true statement from here?

Answer 6

i think you will get 10 = -10, so since its not right, we do not include n =-3, on our answer. okay ?

Answer 7

yes:)

Answer 8

welcome.

Answer 9

there is no mistake in solving that mathematically,but that equation has only one solution x=2......such equations can have only one solution....
x=-3 is not the solution because |n-7| is always positive
so 3n-1 will always be positive,which implies,n must be positive only...

Answer 10

yes, you are right. thanks.
