For this case we have the following equation:

We can rewrite the equation.
For this, we subtract 2.2 on both sides of the equation.
We have then:

Rewriting the equation on both sides we have:

This obtained equation is an equation equivalent to the initial equation.
Answer:
An equation that is equivalent is:
Hi again!
x² + 8x - 20 = 0
Factorize the left side
(x - 2)(x + 10) = 0
Then set factors equal to 0
x - 2 = 0 or x + 10 = 0
x = 0 + 2 or x = 0 - 10
x = 2 or x = -10

Answer:
x = 5
Step-by-step explanation:
In order to obtain a solution, we must assume that the figure is a parallelogram.
Angle BED will be congruent to angle BCD. The sum of angles in triangle BED is 180°, so we have ...
55° +51° +(14x +4)° = 180°
14x = 70 . . . . . . divide by °, subtract 110
x = 5 . . . . . . . . . divide by 14
