Question

Select the correct answer. What is the solution to the equation? -2⁢x−5−4=x

A. -7 and -3
B. 3 and 7
C. -3
D. 7

Answer 1

The solution to the equation -2x - 5 - 4 = x is x = -3 by combining like terms, moving variables to one side and dividing by the coefficient of x.

Step-by-step explanation:

The student has asked for the solution to the equation -2x - 5 - 4 = x.

To solve for x, we need to simplify and isolate x on one side. Here's the step-by-step solution:

1. Combine like terms on the left side: -2x - 9 = x.
2. Add 2x to both sides to get all x terms on one side: -9 = 3x.
3. Divide both sides by 3 to solve for x: x = -3.

Therefore, the solution to the equation is -3, which corresponds to option C.
