Question

Javon and Ivy are both given the equation . Javon thinks the first step is . Ivy thinks the first step is . Who is incorrect and why?

Answer 1

Javon is incorrect because he subtracted 5 from the left side of the equation and added 5 to the right side of the equation

Explanation:

Javon and Ivy are both given the equation 5-2x-1/3=4, Javon thinks the first step is -2x-1/3=9. Ivy thinks the first step is -2x-1/3=-1. Who is incorrect and why?

Given equation:

5 - 2x -1/3 = 4

Javon solution:

first step

-2x - 1/3 = 9

This is solved by subtracting 5 from the left side of the equation and adding 5 to the right side of the equation

5 - 2x -1/3 = 4

5 - 2x -1/3 - 5 = 4 + 5

-2x - 1/3 = 9

Javon is incorrect

Ivy solution:

first step

-2x -1/3 = -1

This is done by subtracting 5 from both sides of the equation

5 - 2x -1/3 = 4

5 - 2x -1/3 -5 = 4 - 5

-2x - 1/3 = -1

Ivy is correct

Javon is incorrect because he subtracted 5 from the left side of the equation and added 5 to the right side of the equation
