Question

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

$a=28,b=11$

Answer 1

From the given data$a=28\&b=11$

We have to verify $a–(-b)=a+b$

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

$$\begin{gathered} =28–(-11) \\ =28+11 \\ =39 \end{gathered}$$

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

$$\begin{gathered} =28+11 \\ =39 \end{gathered}$$

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

Hence, $a-(-b)=a+b$ is verified for the given values of $a$and $b$.
