21 - y = 12 -3.3 - 5y = -5
The steps for solving the given systeni of equations are shown below.
Step 1: -5(21 - y = 12)
-31 - 5y = -5
Step 2: –101 + 5y = -60
-31 - 5y = -5
-13.5 = -65
Step 4:
= 5
Step 5:
2(5) - y = 12
Step 6:
Step 3:
y = -2
Solution: (5,-2)
Select the correct statement about step 3.

easy math just plug in a and b

step-by-step explanation:

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)

493 would be the correct answer
