Please help me with right answer

Answer For Equation One:

2. Add 66 to both sides.

y+6=-\frac{x}{2}

y+6=−  

2 x

3. Multiply both sides by 22.

(y+6)\times 2=-x

(y+6)×2=−x

4. Regroup terms.

2(y+6)=-x

2(y+6)=−x

5. Multiply both sides by -1−1.

-2(y+6)=x

−2(y+6)=x

6. Switch sides.

x=-2(y+6)

x=−2(y+6)

7. Answer is x=−2(y+6)

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)
