Question

6. Verify a - (-b) = a + b for the following values of a and b.
(i) a = 32, b = 18 (ii) a = 275, b = 112 (iii) a = 78, b = 84
(iv) a = 195, b = 27​

Answer 1

Answer:

Solution:

$(i) \: \: \: a - ( - b) = a + b \\ \: \: \: \: 32 - ( - 18) = 32 + 18 \\ \: \: \: \: 32 + 18 = 50 \\ \: \: \: \: \underline{ \underline{50 = 50}} \\ \\ (ii) \: \: \: a - ( - b) = a + b \\ \: \: \: \: 275 - ( - 112) = 275 + 112 \\ \: \: \: \: 275 + 112 = 387 \\ \: \: \: \: \underline{ \underline{387 = 387}} \\ \\ (iii) \: \: \: a - ( - b) = a + b \\ \: \: \: \: 78 - ( - 84) = 78 + 84 \\ \: \: \: \: 78 + 84 = 162 \\ \: \: \: \: \underline{ \underline{162 = 162}} \\ \\ (iv) \: \: \: a - ( - b) = a + b \\ \: \: \: \: 195 - ( - 27) = 195 + 27 \\ \: \: \: \: 195 + 27 = 222 \\ \: \: \: \: \underline{ \underline{222 = 222}} \\ \\ \large Hence, \: \: Verified$

Answer 2

Answer:

1. 50=50

2. 275=275

3. 387=387

4. 162=162

Step-by-step explanation:

1. a-(-b)=a+b

32-(-18)=32+18

32+18=32+18

50=50

2. a-(b)=a+b

275-(-112)=271+112

387=387

ie. the value of LHS = RHS
