Which of the following is a counterexample of x/x=1 for all number x?

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

x – 1 = 0
x • 0 = x
x + 0 = x
x = 1

sometimes true/sometimes false
 
Which of the following is the mathematical sentence of “twice a number decreased by twenty-nine is seven?
29 - 2x = 7
2x -7 -29
2x - 29 = 7
29 - 7 = 2x
 
Which mathematical sentence represents “twelve is eight less than four times a number”?
