x = 12

Step-by-step explanation:

The mid segment is half the sum of the 2 parallel bases, that is

5x - 20 =

5x - 20 = ( multiply both sides by 2 to clear the fraction )

10x - 40 = 6x + 8 ( subtract 6x from both sides )

4x - 40 = 8 ( add 40 to both sides )

4x = 48 ( divide both sides by 4 )

x = 12
