Answer:
x = 6
Step-by-step explanation:
If point M is the midpoint of line KL, then the length of line segment KM equals the length of line segment ML.
⇒ KM = ML
⇒ 2x + 1 = 4x - 11
Subtract 2x from both sides:
⇒ 2x + 1 - 2x = 4x - 11 - 2x
⇒ 1 = 2x - 11
Add 11 to both sides:
⇒ 1 + 11 = 2x - 11 + 11
⇒ 12 = 2x
⇒ 2x = 12
Divide both sides by 2:
⇒ 2x ÷ 2 = 12 ÷ 2
⇒ x = 6
