    y=x for all formula

    There is plus answer as x value for y, when we use 1+1=2 as basic formula. So when we increase number for x value, the number y is same with x because y=x as formula. y=x-a and x is smaller than a, and we increase x value, then y=x value is minus and become zero as y=x as there is y=x.

    But where did you get "y= x" to begin with? And what does this have to do with "1+ 1= 2"?

    y=x-a and x is smaller than a, and we increase x value, then y=x value is minus and become zero as y=x as there is y=x.
    If x is smaller than a, the y is negative but y is NOT equal to x. For example, if a= 5 and x= 4, then y= 4- 5= -1 which is certainly negative but NOT equal to x. If we increase the value of x, while keeping a constant, then when x increases to x= a, y= x- a= a- a= 0. But now y is not necessarily equal to x. If a= 5 and x= 4 as before, increasing x to 4.1, then 4.2, etc. until x= 5, y is 4.1- 5= -0.9, then 4.2- 5= 0.8, etc until x- 5 when y= 0. That happens when x= a, not y= x.
