Step-by-step explanation:
We are given that K is the midpoint of JL. Using this information, we want to find JL.
By the definition of midpoint, this means that:
Substitute them for their equations:
Solve for <em>x.</em> Subtract 8<em>x</em> from both sides:
Add 1 to both sides:
And divide both sides by 6. Hence:
JL is the sum of JK and KL. Hence:
Since JK = KL, substitute either one for the other:
Substitute JK for its equation:
Since we know that <em>x</em> = 2:
Thus:
