Question

Verify$a-(-b)=a+b$ for the following values of $a$and $b$.

$a=21,b=18$

Answer 1

From the given data

$a=21\&b=18$

We have to verify

At first, will consider Left Hand Side$\left(LHS\right)=a–(-b)$

$$\begin{gathered} =21–(-18) \\ =21+18=39 \end{gathered}$$

Then considering Right Hand Side $\left(RHS\right)=a+b$

$=21+18=39$

On comparison $LHS$with $RHS$we get,

$LHS=RHS$

$39=39$

Hence, the value of $a$and $b$is verified
