Solve for k. 8k + 2m = 3m + k

Question

need to find the value of k

Answer 1

So what you need to do is isolate k. Start by subtracting k from both sides:

8k + 2m - k = 3m + k - k

7k + 2m = 3m

From here, you subtract 2m:

7k + 2m - 2m = 3m - 2m

7k = m

If we were isolating m, we would be done, but no. Now we need to divide by 7 so that we can remove that coefficient:

7k / 7 = m / 7

k = ¹/₇ m
