Yes, that looks good.
That's 180 degrees plus every multiple of 360 degrees more.
2k + 17 = 32k = -14k = -7
5k
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
(2k + 3) (2k + 3)
-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
2k + 17 = 32k = -14k = -7
k = 14/43
5k
k=4
36.64
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
Don't know how this found its way onto a maths page! Chemically it's accurate.
(2k + 3) (2k + 3)
8k +2k + 7 = 10k + 7
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
35 + 2k = 9k subtract 2k from each side 35 + 2k - 2k = 9k - 2k 35 = 7k divide both sides integers by 7 35/7 = (7/7)k 5 = k check in original equation 35 + 2(5) = 9(5) 35 + 10 = 45 45 = 45 checks out
-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
