Question

verify that | x+y | = | x | + | y | by taking x = 1/2 and y = -1/4​

Answer 1

Answer:

$x + y = \frac{1}{2} + ( - \frac{1}{4} ) \\ = \frac{1}{2} - \frac{1}{4} \\ = \frac{2 - 1}{4 } \\ = \frac{1}{4} \\ \\ = (x) + (y) = \frac{1}{2} + ( - \frac{1}{4} ) \\ = \frac{1}{2} - \frac{1}{4} \\ = \frac{1}{4} \\ = lhs = whs$
