Answer 2

`\huge\text{Hey there!}`

`\huge\text{Option A. \boxed{\bf \downarrow}}`

`\huge\textsf{- 15 - 3}\\\huge\textsf{= -15 + (-3)}\\\huge\textsf{= \bf -18}\\\boxed{\huge\textsf{\bf -18 \boxed{\\eq} -12}}\\\bullet\huge\text{ \bf Option A. cannot be your result.}`

`\huge\text{Option B. }\boxed{\downarrow}`

`\huge\textsf{-3 - (-9)}\\\huge\textsf{= -3 + 9}\\\huge\textsf{= \bf 6}\\\boxed{\huge\textsf{\bf 6 \boxed{\\eq} -12}}\\\bullet\huge\text{\bf Option B. cannot be your result.}`

`\huge\text{Option C. \boxed{\downarrow}}`

`\huge\textsf{5 - 17}\\\huge\textsf{= 5 + (-17)}\\\huge\textsf{= \bf -12}\\\boxed{\bf -12 \ \boxed{=} -12}\\\huge\text{\bf Option C. could be the result.}`

`\huge\text{Option D. \boxed{\downarrow}}`

`\huge\textsf{-6 - (-6)}\\\huge\textsf{= -6 + 6}\\\huge\textsf{= \bf 0}\\\boxed{\bf 0 \ \boxed{\\eq} -12}\\\huge\text{\bf Option D. cannot be your result.}`

`\boxed{\huge\textsf{Answer: \bf Option C. \underline{\underline{5 - 17}}}}\huge\checkmark`
