#=color(blue)($32,000#

Let the salary of the executive #4# years ago #=x#
So, twice the salary of the executive #4# years ago #=2x#

Present salary of the executive #=$ 51,000#

As per data provided :

#2x - 13,000 = 51,000#

#2x = 51,000+ 13,000#

#2x = 64,000#

#x = (64,000)/2#

#x = $32,000#

Her salary #4# years ago #=$32,000#
