that was wrong answer it is -6
I apologize for the mistake. You are correct. The correct answer is -6.
The equation is:
6 - x - x = 18
Combining like terms, we have:
6 - 2x = 18
Subtracting 6 from both sides, we get:
-2x = 12
Dividing both sides by -2, we get:
x = -6
So, the solution to the equation is x = -6.
To solve the equation 6 - x - x = 18, we can simplify the left side by combining like terms. We have two x terms, so we can rewrite the equation as:
6 - 2x = 18.
To isolate the variable x, we can subtract 6 from both sides of the equation:
-2x = 18 - 6.
Simplifying the right side gives:
-2x = 12.
To solve for x, we divide both sides by -2:
x = 12 / -2.
Simplifying the right side gives:
x = -6.
Therefore, the solution to the equation is x = -6.
