Question

The model below represents 4 x + (negative 4) = negative 2 x + 8.

4 long green tiles and 4 square red tiles = 2 long red tiles and 8 square green tiles.

What is the value of x when solving the equation 4 x + (negative 4) = negative 2 x + 8 using the algebra tiles?
x = negative 4
x = negative 2
x = 2
x = 4

Answer 1

C. x = 2

Explanation:

On edge

Answer 2

x = 2

Explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

6x = 12

`x = (12)/(6) \\ \\ x = 2`
