Question

Verify -(-x)=X for
-4/3

Answer 1

$\rule{400}4$

☆ ANSWER :-

▪︎ Given:-

• Value of x = -4/3

▪︎ To Verify:-

• -(-x) = x.

$\rule{400}2$

▪︎ Concept Used:-

• (-)×(-) = (+)

• (+)×(+) = (+)

• (-)×(+) = (-)

$\rule{400}2$

▪︎ So,

• Let us put the given value of x in the eq.

$\tt\leadsto - ( - x) = x \\ \\ \tt\leadsto - ( - ( - \frac{4}{3} ) = - \frac{4}{3} \\ \\ \tt\leadsto - ( + \frac{4}{3} ) = \frac{ - 4}{3} \\ \\ \tt\leadsto - \frac{ 4}{3} = - \frac{4 }{3} \\ \\ \tt\leadsto \: rhs \: = \: lhs \\\tt hence \: verified$

$\rule{400}4$

▪︎ How I simplify

-(-(-4/3):-

• Here the number is -(-(-4/3)

• So, by applying BODMAS we have to first open the brackets.

• So we had solved the bracket as in brackets it is written (-(-4/3) = +(4/3)

• Now we had solved -(+4/3) = (-4/3)

$\rule{400}4$

▪︎ You can also do it directly when you dont have the any value of x.

• Because -(-x) is always = (x) for any value of x.

$\rule{400}4$

Answer 2

Answer:

if -(-x) = X, then -(-4/3) = 4/3   (minus*minus gives plus)
