since the line contains a midpoint, both sides of the line will be equal each other and exactly one half of the entire line

so basically ed = df
and ed + df = ef

first, we find the value of x

2(3x + 1) = 4x + 12

6x + 2 = 4x + 12

2x = 10

x = 5

plug x back into the equation for ef

4(5) + 12 = ef

20 + 12 = ef

32 = ef
