Question

verify -(x+y)=(-x)+(-y) when x=-¾ and y= -⅝​

Answer 1

Step-by-step explanation:

Let's take LHS =>(-x)+(-y)

=>-(-3/4)+-(-5/8)

=>44/32

LHS =>11/8

Now. RHS =>-(x+y)

=>-[(-3/4) + (-5/8)]

=>-[-44/32] =>-[-11/8]

i.e RHS =>11/8

Hence,RHS =LHS

Answer 2

Answer:

$- (x + y) = ( - x) + ( - y)$

.

$x = - \frac{3}{4}$

$y = - \frac{5}{8}$

$(- ( - \frac{3}{4} )) + ( - ( - \frac { 5}{8} ))$

$= \frac{3}{4} + \frac{5}{8}$

= $\frac{(3 \times 2) + (5 \times 1)}{8}$

= $\frac{6 + 5}{8}$

= $\frac{11}{8}$

Note :

( + ) x ( + ) = ( + )

( - ) x ( - ) = ( + )

( - ) x ( + ) = ( - )

( + ) x ( - ) =( - )
