Question

Find the solution: |x - 3| = 8, x ∈ R.

a) {1, 2}
b) {2, -4}
c) {-5, 11}
d) {5, -11}​

Answer 1

Answer:

c) {-5, 11} is the right answer

Step-by-step explanation:

We know that, if |x| = a, then x = ±a

So, if |x - 3| = 8, then

x - 3 = ± 8

• If x - 3 = 8

x = 8 + 3

x = 11

• If x - 3 = -8

x = -8 + 3

x = -5

So, x = -5, 11
