Question

B) verify a –(-b) = a + b for the following values of a and b.a = 15, b = 9

Answer 1

Given:

$\sf a=15,b=9$

To verify:

$\sf a-(-b)=a+b$

Explanation:

L.H.S:

$\sf Substituting\:the\:values\:of\:a\:and\:b,\:we\:get:$

$\Rightarrow\sf 15-(-9)$

$\Rightarrow\sf 24$

R.H.S:

$\sf Substituting\:the\:values\:of\:a\:and\:b,\:we\:get:$

$\Rightarrow\sf 15+9$

$\Rightarrow\sf 24$

$\sf a-(-b)=a+b$

$\sf 24=24$

Hence proved.
