Question

verify -(-x) = x for x = 13/19​

Answer 1

Step-by-step explanation:

we know that minus of minus that is, - × - = +

Hence (-) × (-x) = x

Now, from the given value of x = 13/19, let us verify

$-(-\frac {13}{19}) = (-)(-)(\frac{13}{19})\\\\\implies + \frac{13}{19}\\\\\implies \mathrm {\frac{13}{19}}\\\\ Hence \ Verified!!\\ \\ \bigstar \ \huge {\textsf {Hope it helps!!}} \ \bigstar\\ \bigstar \ \huge {\textsf {Please mark as brainliest}} \ \bigstar$

Answer 2

The statement is true -(-x) = x for x = $\frac{13}{19}$ when product of two negative numbers is always positive.

Given that,

We have to verify -(-x) = x for x = $\frac{13}{19}$

We know that,

What is the negative?

The product of two negative integers is always positive since negative multiplied by itself is a positive number.

Any number higher than 0 is a negative number. Positive numbers are those that start at zero. Positive and negative numbers can be added to, subtracted from, multiplied, or divided according to certain laws.

So,

-(-x) = x

-(-$\frac{13}{19}$) = $\frac{13}{19}$

$\frac{13}{19}$ = $\frac{13}{19}$

Therefore, the statement is true -(-x) = x for x = $\frac{13}{19}$
