#n= 9#

Explanation:

Given: # " " -7= 1 + 2/3 n#

Step 1: Subtract 1 to both side to get

#7 color(red)(-1) = color(red)(-1) + 1 +2/3 n #
#6 = 2/3 n #

Step 2: Multiply by the reciprocal to both side of the equation to get

#6color(blue)((3/2)) = color(blue)(3/2) 2/3n#
#((cancel2*3)/1)color(blue)((3/cancel(2)) = color(blue)(cancel(3/2) (cancel(2/3))n#

#9= n#

Answer: #n= 9#
