If $$2x - 6 = x - 9$$, then $$x =$$

(A) -9
(B) -6
(C) -3
(D) 2
(E) 6

Given: $$2x - 6 = x - 9$$
Subtract $$x$$ from both sides of the equation to get: $$x - 6 = -9$$
Add $$6$$ to both sides of the equation to get: $$x = -3$$

Cheers,
Brent

Solution

Given
In this question, we are given that
• An equation: 2x – 6 = x – 9

To find
We need to determine
• The value of x

Approach and Working out
Simplifying the given equation, we get
• 2x – 6 = x – 9
Or, 2x – x = -9 + 6
Or, x = -3

Thus, option C is the correct answer.
