The midpoint of the segemnt with endpoints (x1, y1) and (x2, y2) is the average for each coordinate. This is the ordered pair:\[(\frac{ x _{1}+x _{2} }{ 2 }, \frac{ y _{1} y _{2} }{ 2 })\]For the moment, just looking at the ycoordinate, you'll see that the midpoint value of 6 is determined by averaging 7 and 5. So, for the xcoordinate, you average x2 and 1 to get 4. [x2 + (1)] / 2 = 4 x2  1 = 8 so, x2 = 7.

typo: the ordered pair for y is also supposed to be "+"

(y1 + y2)/2 that is. Accidentally hit the minus sign.
