WA says '7x/x = 7' only if x ? 0, but has no problem with 'ax/x = a'. Why? In WA, entering 'ax/x = a' will return 'True.' If 'a' is replaced with a constant, it changes its rule. '7x/x = 7' will say that it's true as long as x ? 0. Why is it that 'ax/x = a' is true until 'a' is replaced with a constant? AUTHOR: C R 4512VIEWS 1REPLIES 7 years ago
