(x - 1)2/3 = 4​

5

Step-by-step explanation:

2/3x-2/3=4

2/3x=3 1/3

14/3

Step-by-step explanation:

x-1×⅔=4

x-⅔=4

×=4+⅔

x=14/3

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
