Tell whether the statement below is always, sometimes, or never true. equation like, a + 4 = 8 and 4 - m = 2 have exactly one solution.

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
