Question

4. Find the value of (a + b)) and (a - b), if a = 5 and b = 7.​

Answer 1

(a+b) =12

(a-b) =. - 2

Explanation:

You will put the numbers given as a=5 and b=6

In to the value of (a+b) and (a-b)

So it will be

*(a+b) =(5+7)

=(12)

*(a-b) =(5-7)

=(-2)

Answer 2

if a=5 and b=7 so (a+b)=(5+7)=12

(a-b)=5-7= -2
