Answer 1

N 1 we have

`\begin{gathered} \lvert-6+4\rvert=\lvert-6\rvert+\lvert4\rvert \\ \lvert-2\rvert=6+4 \\ 2=10 \end{gathered}`

False

N 2

`\begin{gathered} \lvert\lvert2-8\rvert=\lvert2\rvert-\lvert8\rvert \\ \lvert-6\rvert=2-8 \\ 6=-6 \end{gathered}`

False

N 3

`\begin{gathered} \lvert7+5\rvert=\lvert7\rvert+\lvert5\rvert \\ \lvert12\rvert=7+5 \\ 12=12 \end{gathered}`

True

N 4

`\begin{gathered} \lvert-3-1\rvert=\lvert-3\rvert-\lvert1\rvert \\ \lvert-4\rvert=3-1 \\ 4=2 \end{gathered}`

False

N5

`\lvert-2+(-4)\rvert=\lvert-2\rvert+`
`\begin{gathered} \lvert-6)\rvert=2 \\ 6=2 \end{gathered}`

False
