Helen wrote and solved the equation. x minus 17 = 56. X minus 17 + 17 = 56 minus 17. X = 39. What was Helen's error? Helen only needed to add 17 to the left side of the equation. Helen should have added 17 to both sides of the equation. Helen's work is correct. Helen made a subtraction error when subtracting 17 from 56.

 Helen should have added 17 to both sides of the equation.

Step-by-step explanation:

Hi, to answer this question we have to analyze Helen's Work:

X-17 =56

X-17+17 =56-17

X =39

In the second step she made a mistake, she added 17 to the left side of the equation and subtracted 17 to the right side of the equations.

Helen should have added 17 to both sides of the equation.  

The correct way is:

X-17 =56

X-17+17 =56+17

X =73
