Solve for x:

- (x) / (2) - 1 = 0

Put each term in - (x) / (2) - 1 over the common denominator 2: - (x) / (2) - 1 = (-2) / 2 - (x) / 2:

(-2) / 2 - x/2 = 0

(-2) / 2 - x/2 = (-x - 2) / 2:

(-x - 2) / 2 = 0

Multiply both sides of (-x - 2) / 2 = 0 by 2:

(2 (-x - 2)) / 2 = 2*0

(2 (-x - 2)) / 2 = 2/2 * (-x - 2) = - x - 2:

-x - 2 = 2*0

0*2 = 0:

-x - 2 = 0

Add 2 to both sides:

(2 - 2) - x = 2

2 - 2 = 0:

-x = 2

Multiply both sides of - x = 2 by - 1:

(-x) / (-1) = - 2

(-1) / (-1) = 1:

Answer: x = - 2
