Question

If x = -2/8 and y = ¼, find (x+y) + (x - y )​

Answer 1

Answer:

-½

Step-by-step explanation:

$x = \frac{ - 2}{8} \: and \: y = \frac{1}{4} \\ (x + y) = \frac{ - 2}{8} + \frac{1}{4} = \frac{ - 2 + 2}{8} = \frac{0}{8} = 0 \\ \\ (x - y) = \frac{ - 2}{8} - \frac{1}{4} = \frac{ - 2 - 2}{8} = \frac{ - 4}{8} = \frac{ - 1}{ 2} \\ (x + y) + (x - y) = 0 + \frac{ - 1}{2} = \frac{ - 1}{2}$
