Question

Verify: a-(-b) = a+b for the values a=52 and b=21

PLEASE WITH EXPLANATION ​

Answer 1

Answer:

To Verify:-

• a-(-b)=(a+b)

Given:-

• a=52
• b=21

Solution:-

Substituting the values accordingly

52-(-21)=52+21

we know bracket sign implies multiplication

therefore - × - = +

therefore

52+21=52+21

73=73

L.H.S=R.H.S

hence verified

Answer 2

Step-by-step explanation:

$a - ( - b) = a + b \\ a = 52 \: and \: b = 21\\ \\R.H.S, \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ a -( - b) \\ = 52 - ( - 21) \\ = 52 + 21 \\ = 73 \\ \\ L.H.S, \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ a + b \\ = 52 + 21 \\ = 73 \\ \\ .'. \: a - ( - b) = a + b \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (verified)$
