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

What is the answer to 35 plus 2k equals 9k?
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
What is the solution to 2k plus 17 equals 3?
2k + 17 = 32k = -14k = -7

If 2k-1 equals 0 then k equals?
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
What is the solution to 2k plus 17 equals 3?
2k + 17 = 32k = -14k = -7
2k plus 42 times 2k plus 4 equals 32?
k = 14/43
What are the possible values of k in the quadratic equation x squared plus 5kx plus 2k equals 0 which has equal real roots?

K - 20 equals 2k - 13?
k=-7
2k plus 3 equals 11 what is k?
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
What does odd X even equal?
Let even be of the form 2k and odd be of the form 2k+1. Then odd * even becomes 2k*2k+1, or 4k^2 +2k. This can be written as 2(k^2 + k), which is of the form 2k. Therefore, odd X even equals even.
