absolute value of x15 is less than 18 Solve and write answer

absolute value of x+15 is less than 18

Solve and write answer in Interval Noatation

Solution

| x+15 | < 18

for : x+ 15 >0 ; x + 15 <18

x < 3

for x+ 15 <0 ; -x - 15 < 18

x > -33

Solution : -33 < x < 3

Interval notation : with open intervals as we dont have equalto sign with less than like <=( -33 , 3 )

So, ( -33 , 3)
