2*5k or 10k are equivalent.
5k + 2 = -2 Therefore, 5k = -4 k = -4/5 k = -0.8

-4k + 10 - k + 2 = 2k + 4k + 18Combine all the 'k' terms on the left side:-5k + 10 + 2 = 2k + 4k + 18Combine all the 'k' terms on the right side:-5k + 10 + 2 = 6k + 18Combine the numerical terms on the left side:-5k + 12 = 6k + 18Add 5k to each side:12 = 11k + 18Subtract 18 from each side:-6 = 11kDivide each side by 11:k = -6/11
k + 5k = 6k 2 x 3 x k
5k + 7 + 3k can be simplified into 8k + 7

9k + 8
k = 2 7 + (5 x 2) = 17 (8 x 2) + 1 = 17
7k + 4 + 4k - 9 - 5k (7k + 4k - 5k) + (4 - 9) 6k + -5 6k - 5
-12 + 5k = -925k + (-12) = -925k = -92 + 125k = 80k = -80/5k = -16
