Step 1: Let's recall that a segment bisector is a ray or segment which cuts another line segment into two equal parts.

Step 2: Upon saying that, we have:

DS = SE

Step 3: Replacing with the equation we have to solve for x:

4x + 12 = 8x - 8

4x - 8x = - 8 - 12

-4x = -20

Dividing by - 4

-4x/-4 = -20/-4

x = 5

Step 4: If x = 5, let's find the length of DS and SE:

4 * 5 + 12 = 8 * 5 - 8

20 + 12 = 40 - 8

32 = 32

Step 5: x = 5 and DS/SE = 32
