Пошаговое объяснение:

X - 2X - 5 = 40

-х =40+5

х= -45

Answer 2

Let's solve the equation step by step to find the correct value of X:

X - 2X - 5 = 40

Combine like terms:

-X - 5 = 40

Now, let's isolate X on one side of the equation. To do that, we need to get rid of the constant term (-5) on the left side. To achieve this, we can add 5 to both sides of the equation:

-X - 5 + 5 = 40 + 5

Simplify:

-X = 45

Now, to isolate X, we need to get rid of the coefficient of -X, which is -1. To do that, we can multiply both sides of the equation by -1:

-1 * -X = -1 * 45

Simplify:

X = -45

So, the correct value of X is -45, not 35.
