Question

6. If a=-8 and b = -7, show that a-b=b-a.​

Answer 1

$a = - 8 \\ b = - 7$

$a - b = b - a \\ - 8 - ( - 7) = - 7 - ( - 8) \\ - 8 + 7 = - 7 + 8 \\ - 1 \not = + 1$

Answer 2

Answer:

$\begin{gathered}a = - 8 \\ b = - 7\end{gathered}</p><p> \\ \begin{gathered}a - b = b - a \\ - 8 - ( - 7) = - 7 - ( - 8) \\ - 8 + 7 = - 7 + 8 \\ - 1 \not = + 1\end{gathered}$
