What is the question? If you are only trying to expand the
expression then the answer would be:
1/4 (5y-3)+ 1/16 (12y+17)
(5y/4) – (3/4) + (12y/16) + (17/16)
1.25y – 0.75 + 0.75y + 1.0625
2y + 0.3125
If you are trying to find for y, then you forgot to equate
it to 0, that is:
2y + 0.3125 = 0
2y = -0.3125
<span>y = 0.15625</span>
Where’s the quote ? You didn’t provide it
Standard form is when x and y are on one side of the equations and the constants are on the other side. Moving the variables and constants around we get,

However we have to make sure the x is not negative. Multiplying all by negative one we get x-y=-1
Given:
The midpoint of segment AB has the coordinates M(-4,2).
The coordinates of endpoint A are (-6, -7).
To find:
The coordinates of B.
Solution:
Let the coordinates of point B are (a,b).
Formula for midpoint:

The midpoint of segment AB has the coordinates M(-4,2), so by using the above formula we get


On comparing both sides, we get




And,




Therefore, the coordinates of point B are (-2,11).
