Question

I don't get it can u please show me how to do it step by step ​

Answer 1

the first one would be
x-6=5
x-6=-5
x=11
x=1
so the answer would be x1 = 1, x2 = 11

Answer 2

Explanation:

6.)

|x - 6| = 5

x + 6 = 5

x = 5 - 6

x = - 1

7.)

|3x - 7| = 12

3x + 7 = 12

3x = 12 - 7

3x = 5

x = 5/3

8.)

|2x + 9| - 10 = 5

2x + 9 - 10 = 5

2x - 1 = 5

2x = 1 + 5

2x = 6

x = 6/2

x = 3
