N=1/2MP? Since n would be the midpoint you have to divide the segment into two.
what is the question.......
If you could zoom in the pic it would be great
<em>multiply the numbers.</em>
4 x 6 + y = 20
<em>move constant (24) to the right side and change its sign.</em>
24 + y = 20
<em>calculate the difference and you get the answer.</em>
y = 20 - 24
y = -4
So the value of y is -4.
