Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The first step I would do is to subtract the 2x from both sides so the answer is choice D.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
