Just count by tens
7y +8= 9+3y+2y
Combine like terms.
7y+8= 9+5y
Subtract 5y on both sides.
2y+8=9
Subtract 8 on both sides.
2y=1
Your answer is 2y=1
I hope this helps!

Answer:
The coordinates are (0,b)
Step-by-step explanation:
Here, we want to find the coordinates of the midpoint F
as we can see, F is between A and B
we proceed to use the midpoint formula
The midpoint formula is;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
(x1,y1) = (-3a, b)
(x2,y2) = (3a, b)
The substitution of these values will thus yield;
(-3a + 3a)/2, (b + b)/2
= (0/2), (2b/2)
= (0, b)
