EXPLANATION

Let's see the facts:

Midpoint = (-2,5)

A=(4,7)

Let the point of B as B=(x,y)

Then,

Multiplying the frist equation by 2:

$x+4=-2\cdot2$

Subtracting -4 to both sides:

Simplifying:

Multiplying the second equation by 2:

$y+7=2\cdot5$

Subtracting -7 to both sides:

$y=10-7=\text{ 3}$

The coordinates of the point B are:

B=(-8,3)
