Question

Problem:A number decreased by negative three is equal to -40. Write an equation and find the number.

Would the equation be X-3=-40 or X-(-3) =-40

It saying decreased makes it a subtraction problem so you obviously have one negative sign already then would you also add another negative sign in front of the 3 as it calls for a negative 3? Sort of confused. Thank you <3

Answer 1

well let's start by letting out unknown number be x.
So a number DECREASED by -3 = -40
so x - ( -3) = -40
And two negatives make a positive :)
So it would become x + 3 = -40

YES RIGHT :) 2nd one
