5k
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
Add 17 to each side and collect like terms: 2k = 17 + 4 - 21k - 6 ie 2k = 15 - 21k so 23k = 15 which suggests that you may have mistyped your question.
(2k + 3) (2k + 3)
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
k = 14/43

Don't know how this found its way onto a maths page! Chemically it's accurate.

4k + 24 = 6k - 10 subtract 4k from each side 4k - 4k + 24 = 6k - 4k - 10 24 = 2k - 10 add 10 to each side 10 + 24 = 2k - 10 + 10 34 = 2k divide each side integers by 2 17 = k ------------check 4(17) + 24 = 6(17) - 10 68 + 24 = 102 - 10 92 = 92 checks
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
