Question

–(k + 9) – 8 = –4k – 9

Answer 1

`-(k + 9) - 8 = -4k - 9\\ -k-9-8=-4k-9\\ 3k=8\\ k=(8)/(3)`

Answer 2

`\sf-(k+9)-8=-4k-9`

Distribute -1 into the parenthesis:


`\sf-k-9-8=-4k-9`

Combine like terms:


`\sf-k-17=-4k-9`

Add 17 to both sides:


`\sf-k=-4k+8`

Add 4k to both sides:


`\sf3k=8`

Divide 3 to both sides:


`\sf~k=(8)/(3)~or~2(2)/(3)`
