Question

Verify a– (-b) = a+b

when a = 45, b = -30​

Answer 1

Step-by-step explanation:

We have to verify a - (-b)= a+b

Where a = 45 b = -30

substituting the value of a and b

$a - ( - b) = a + b \\ 45 - ( - ( - 30)) = 45 + ( - 30) \\ 45 - ( + 30) = 45 - 30 \\ 45 - 30 = 45 - 30 \\ 15 = 15$

Hence Verified
