Question

Verify $a-\left(-b\right)=a+b$for the values of $a=275$and $b=112$

Answer 1

Verify $a-\left(-b\right)=a+b$for the values of $a=275$and $b=112$

$a-\left(-b\right)=a+b$

L.H.S$=a-(-b)$

$$\begin{gathered} =275-(-112) \\ =275+112 \\ =387........\left(1\right) \end{gathered}$$

R.H.S$=a+b$

$$\begin{gathered} =275+112 \\ =387......\left(2\right) \end{gathered}$$

from$\left(1\right)$ and$\left(2\right)$, we get

L.H.S$=$R.H.S
