3k-5=7k+73k-7k=7+5-4k=12k=-3
-6k+7k = 1k or normally k on its own.
The answer is 13k .
3k+4m+2
17k2-4k+19-14k2-16-7k-11k2=-8k2-11k+3
-6K+7K=1K or K
-6k + 7k = k
1k
7(k + 5)(k - 4)
3k-5=7k+73k-7k=7+5-4k=12k=-3
-6k+7k = 1k or normally k on its own.
The answer is 13k .

k(7k + 9)
answer=3k-3
17k2-4k+19-14k2-16-7k-11k2=-8k2-11k+3
35k2 - 22k + 3 = 0 35k2 - 15k - 7k + 3 = 0 5k(7k - 3) - (7k - 3) = 0 (5k - 1)(7k - 3) = 0 5k -1 = 0 or 7k - 3 = 0 5k = 1 or 7k = 3 k = 1/5 or k = 3/7
