2k = 5k-30

Subtract 5k from both sides:

-3k = -30

Divide both sides by -3 to find the value of k remembering that a minus divided into a minus becomes a plus:

k = 10

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

2k + 17 = 32k = -14k = -7

Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
