Question

Which equation is modeled below? 1 negative x tile and 1 positive 1 tile = 2 x tiles and 3 positive 1 tiles

a. Negative x + 1 = 2x + 3
b. x + Negative 1 = 2x + 3
c. x + Negative 1 = 3x + 2
d. Negative 2x = 2x + 3

Answer 1

The equation modeled below is option c. x + Negative 1 = 3x + 2.

Step-by-step explanation:

The equation modeled below is option c. x + Negative 1 = 3x + 2.

To determine the equation, we can look at the number of the x tiles and positive 1 tiles on each side of the equation. On the left side, we have 1 negative x tile and 1 positive 1 tile. On the right side, we have 2 x tiles and 3 positive 1 tiles.

Therefore, the equation can be written as x + (-1) = 3x + 2.
