Simple....
you have:
to convert them into improper fractions:
1.) Take whole number*denominator
(5*5=25)
2.) Take what you got...and add the numerator
(25+2=27)
3.) Use the original denominator
Do the same to the other one...
2*13=26
26+10=36
Now..add...
But..you need a common denominator!
Now you can add!
When simplified....
Thus, your answer.

We were given the points, A(5,-3) and the midpoint of AB, M(-4,2).
Let point B have coordinates (c , d).
Then the midpoint of A(5, -3) and B(c,d)
Now let us compare to the given midpoint M(-4, 2).
We can then write the following equations for the corresponding coordinates.
Comparing x coordinates, we have;
Multiplying both sides of the equation by 2 gives,
5+c = 2(-4)
Simplifying the right hand side gives,
5 + c = -8
Grouping like terms, we have,
c = -8 - 5
This simplifies to,
c = -13
Comparing y coordinates we have,
Multiplying through by 2 gives,
-3 + d = 2(2)
This means that,
-3 + d = 4
Making the subject we have,
d = 4+3
This implies that,
d = 7
Hence the coordinates of B are (-13,7).
