2x - 5y + 3 = 6x - 3y + 7. If x = 4, what is the value of y?

y = - 10

Step-by-step explanation:

2x - 5y + 3 = 6x - 3y + 7

2(4) - 5y + 3 = 6(4) - 3y + 7

8 - 5y + 3 = 24 - 3y + 7

11 - 5y = 31 - 3y

11 - 11 - 5y = 31 - 11 - 3y

- 5y = 20 - 3y

- 5y + 3y = 20 - 3y + 3y

- 2y = 20

- 2y ÷ - 2 = 20 ÷ - 2

y = - 10

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)
