Answer:
Solving quadratic equations can be difficult, but luckily there are several different methods that we can use depending on what type of quadratic that we are trying to solve. The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Step-by-step explanation:

3/2x + 1/5x = 11/6x - 2/15....to get rid of fractions, multiply by common denominator, which is 30.
45x + 6x = 55x - 4
51x = 55x - 4
51x - 55x = -4
-4x = -4
x = -4/-4
x = 1
Answer:
The answer is 2 1/2 or in mixed form 5/2

<h3>Given:</h3>
angle CED = 45°
angle EDC = x
angle DCE = 2x
<h3>To Find:</h3>
The value of x.
<h3>Angle Sum Property:</h3>
The sum of all the Interior Angles of a triangle is 180°.
<h3>Solution:</h3>
x + 2x + 45° = 180°
or, 3x = 180° - 45°
or, 3x = 135°
or, x = 135/3 = 45°
<h2>Answer:</h2>
The value of x is 45°.
