PLEASE GIVE ME MY FAVOURITE HEART FROM MY CUTE SIS...☺️
Step-by-step explanation:
The reciprocal means the multiplicative inverse of a number.
The multiplicative inverse #n'# of a number #n# is a number that when multiplied to #n#, results to the multiplicative identity which is 1.
That is...
#n'*n = 1#
#-2/3x = 1#
#-2x = 3#
#x = -3/2#
