Answer:
[tex]I-3I=3[/tex]
Step-by-step explanation:
I I if these two lines surround a number or a expression it means that the expression will now be a positive expression because of absolute value.
In this case we have I-3I because the lines surround the negative three it will turn into a positive three. Same with any expression...
[tex]I-3+-4I[/tex]
[tex]= 3+4[/tex]
[tex]3+4=7[/tex]
[tex]=7[/tex]
Hope this helps.
