Slove for x

15(x + 1) + 10(x) = 30(4) - 6( 2x - 1)   multiplied by 30 to clear the denominator

15x + 15 + 10x = 120 -12x + 6           distributed

25x + 15 = 126 - 12x                        added like terms

37x + 15 = 126                                 added 12x to both sides

37x = 111                                          subtracted 15 from both sides

   x = 3                                            divided both sides by 37

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)
