Question 1168254
Find all values satisfying the equation 

Enter your answers in increasing order.|x-9| = 3.
x= ?
x= ?
solution 
we know that
 |x| =x  when x is greater than 0 x>0
|x| =-x  when x<0 using above property of modulus 
|x-9| = 3
x-9=3   or -x+9=3
x=3+9 or -x=3-9
x=12 or -x=-6
x=12 or x=6
