Final answer:
In the equation 27 = 46 + 2x - x, the x's represent the value of x, which is the variable we are solving for.
Step-by-step explanation:
The x's in the equation 27 = 46 + 2x - x stand for the variable that we are trying to solve for. To solve for x, we combine like terms on the right side of the equation, which results in 27 = 46 + x. Then, we isolate the variable x by subtracting 46 from both sides to get -19 = x. Therefore, the x's represent the value of the variable x we are looking for. The correct answer to what x's represent in the given equation is: b) The value of x.
