Which equation is modeled below?

4 x tiles and 2 negative 1 tiles = 2 x tiles and 4 1 tiles.

2 x + (negative 2) = negative 2 x + 6
4 x + (negative 2) = negative 2 x + 6
2 x + 4 = 6 x + 2
Negative 2 x + 4 = 6 x + (negative 2)

1 answer

Let's analyze the equation based on the information provided in the question.

The equation represents the following terms:

  • "4 x tiles" can be considered as \(4x\).
  • "2 negative 1 tiles" is the same as \(-2\).
  • "2 x tiles" is \(2x\).
  • "4 1 tiles" is simply \(4\).

Based on this interpretation, we can express the equation as:

\[ 4x - 2 = 2x + 4 \]

Now, let's rearrange this equation to see if it matches any of the options:

Starting from \(4x - 2 = 2x + 4\):

  1. Add \(2\) on both sides: \[ 4x = 2x + 6 \]

  2. Subtract \(2x\) from both sides: \[ 2x = 6 \]

This equation doesn't exactly mirror any of the given options, but if we rewrite the original equation \(4x - 2 = 2x + 4\) in the option forms given, we can see that:

  • We can rearrange \(4x - 2 = 2x + 4\) to get to \(4x - 2x = 4 + 2\), which simplifies to \(2x + 2 = 6\).

None of the options provided precisely match this rearrangement. However, if we look at the second option:

\(4x + (negative 2) = negative 2x + 6\)

Which can be simplified to:

\[ 4x - 2 = -2x + 6 \]

This does capture the structure of \(4x - 2\). Therefore, the equation modeled is best represented by this option:

Answer: \(4x + (negative 2) = negative 2x + 6\).
