# Verify a-(-b) = a+b for the following values 'a' and 'b' (i) a = 75, b = 84 (ii) a = 118, b = 125 (iii) a = 25, b = 130

The given expression is based on addition and subtraction of integers

## Answer: The given expression a-(-b) = a + b holds true for all given pairs of a and b.

Let's verify the given expression

## Explanation:

a - (- b) = a + b

i) when a = 75 and b = 84

LHS = 75 - (- 84) = 75 + 84 = 159

RHS = 75 + 84 = 159

Hence, LHS = RHS

ii) when a = 118 and b = 125

LHS = 118 - (- 125) = 118 + 125 = 243

RHS = 118 + 125 = 243

Hence, LHS = RHS

iii) when a = 25 and b = 130

LHS = 25 - (- 130) = 25 + 130 = 155

RHS = 25 + 130 = 155

Hence, LHS = RHS

### Thus, the given expression a-(-b) = a + b holds true for all values of a and b.
