Question

any help would be great

The sum of 2 consecutive integers is equal to their difference.

Answer 1

Let the two consecutive numbers be x and x+1
translating "The sum of 2 consecutive integers is equal to their difference" ---> x + x+1 = x+1 - x

I trust you to solve for x

Answer 2

x + x + 1 = x + 1 - x

-x + x + x + 1 = x + 1 -x + -x

= x + 1 = x + 1 = 2x

x = 1 = 1 = x + 1 -1 - 2x

x = x = 2x

3 = 3 - 2 * 3 = [-3]

Answer 3

x + x + 1 = x + 1 = x

x + x + x + 1 = x + 1 - x + x

3x + 1 = x + 1

-x + 3x + 1 = -x + x + 1

2x + 1
