Question

3. What is the solution of 3x - 5] + 2 = 20?OX = -6 or x = 6Ox= -1 or x = 11OX = -11 or x = 11Ox = -11 or x = 1

Answer 1

3 |x -5| + 2 = 20

we are going to solve for |x - 5|

|x-5| = (20 - 2) / 3 = 18 / 3 = 6 then |x - 5| = 6

|x - 5| means absolute value of x - 5, so we will take the positive value of x -5 even when it is negative

x - 5 = 6 solving for x gives us x = 11

if x is negative, then -x - 5 = -6 then x = -1

So the answer would be the second option -1 and 11
