answer:

[tex]r - 1[/tex]

Step by step explanation:

Step 1: Distribute

[tex]( - r - 5) - ( - 2r - 4) \\ ( - r - 5) + 2r + 4[/tex]

Step 2: Eliminate redundant parenthesis

[tex]( - r - 5) + 2r + 4 \\ - r - 5 + 2r + 4[/tex]

Step 3: Add numbers

[tex] - 3 \purple{ - 5} + 2r + \purple{4} \\ - r \purple{ - 1} + 2r[/tex]

Step 4:Combine like terms

[tex] \purple{ - r } - 1 + \purple{2r} \\ \purple{1r} - 1[/tex]

Step 5:Multiply by 1

[tex]1r - 1 \\ r - 1[/tex]
