Answer:
- 18
Step-by-step explanation:
- 7 ( k + 5 ) = 3k - ( 8k - 1 )
- 7 ( k ) - 7 ( 5 ) = 3k - ( 8k ) - ( - 1 )
- 7k - 35 = 3k - 8k + 1
- 7k - 35 = - 5k + 1
( Add the alphabetical terms and numbers separately )
Add 5k on both sides,
- 7k + 5k - 35 = - 5k + 5k + 1
- 2k - 35 = 1
Add 35 on both sides,
- 2k = 1 + 35
- 2k = 36
Divide - 2 on both sides,
k = 36/-2
k = - 18
Hence,
the value of k is - 18.
