Answer 2

$\huge \text{Question - }$

Verify a - (-b) = a + b for the following values of a and b.

a = 50 b = 21

$\huge \text{Required Answer - }$

Given -

• a = 50
• b = 21

LHS -

$:\implies\sf{a-(-b) }$

By substituting the value of a and b as , a = 50 b = 21

$:\implies\sf{50-(-21) }$

Now we know that (-) and (-) is (+) hence ,

$:\implies\sf{50+21}$

$:\implies\sf{71}$

RHS -

$:\implies\sf{a+b }$

by substituting the value of a and b as , a = 50 b = 21

$:\implies\sf{50+21 }$

$:\implies\sf{71}$

Hence ,

71 = 71

LHS = RHS
