Question

Solve 2|x + 1| - 6 ≤ 7 and graph the solution set in a number line.

Solution :

2|x + 1| - 6  ≤  7

Add 6 to each side. 

2|x + 1|  ≤  13

Divide each side by 2. 

|x + 1|  ≤  13/2

 x + 1  ≤  13/2

x  ≤  11/2

 x + 1  ≥  -13/2

x  ≥  -15/2

Combine the above two inequalities.

-15/2  ≤  x  ≤  11/2

So, the solution is

[-15/2,  11/2]
it's right or wrong ???​
