If the difference between 21 and k is 48. Find the value of K
#Please anyone to help me this question#
Can the value of K be -27.
yes, you want:
|k-21| = 48
so,
k-21 = 48 OR -k+21 = 48
k = 69 or k = -27
think of a number line and place a dot at 21
now count 48 places to the right ---> 69
and count 48 places to the left -----> -27
