For this case we have the following equation:
Step 1 of the solution is to make the distributive property.
We have then:
Step 1 is correct.
The step is to combine similar terms. Caleb wrote:
He wrongly combined the similar terms on the right side of the equation.
The correct solution is:
Answer:
In step 2, the like terms were not combined on the right side of the equation.

Answer:
We need to demontrate
As you can see in the figure below, angle MJL is an inscribed angle for Circle M, that means we can use the inscribed angle theorem to demonstrate the proposition above.
<h3>Therorem.</h3><em>The angle formed by two intersecting chords with vertex on the circumference is equal to one-half of the intercepted arc.</em>
<em />
Notice that the theorem says a chord. However, a diameter is a chord by definition, because a chord is a segment that unites to points of the circumference, and a diameter does that too.
Therefore, based on the inscribed angle arc theorem, we have
