Question

What is the solution of |x – 4| – 10 = 1?

x = –15 or x = 15
x = –11 or x = 11
x = –7 or x = 15
x = –15 or x = 7

Answer 1

Choice C is correct.

Explanation:

We have given the equation:

|x – 4| – 10 = 1

We have to find the solution of equation.

Ix-4I - 10 =1

Ix-4I = 1+10

Ix-4I = 11

(x-4) = 11 or -(x-4)= 11

x = 11+4 or -x+4 = 11

x = 15 or -x = 7

x=15 or x= -7

choice C is correct.
