Question

Giardo is using the model below to solve the equation 3×+1 = 4×+(-4) which step could be adjusted so that Gerardo final step results in a positive x value

Answer 1

The correct option is B.

In step one he should have added 3 negative x-tiles to both sides.

Explanation:

Given the equation

3x + 1 = 4x + (-4)

Adding 3 negative x tiles, we have

3x + 1 + (-3x) = 4x + (-4) + (-3x)

1 = x - 4

x = 1 + 4 = 5

Answer 2

The answer is B. In step one he should have added 3 negative x-tiles to both sides.
