Question

The model below represents an equation. Which value of x makes the equation true?

A) x = -1/4
B) x = 4
C) x = -1/2
D) x= -4

Answer 1

x = -1/4

Explanation:

The large rectangles are x and there are 4 plus 4 ones = 3 ones

4x + 4 = 3

Subtract 4 from each side

4x+4-4 = 3-4

4x = -1

Divide each side by 4

4x/4 = -1/4

x = -1/4
