That's two different questions. Suppose I demonstrate the answer to the first one,
and when I'm finished doing that, you'll have the answer to the second one.
2/3 + 3K/4 = 71/12
Multiply each side of the equation by 12:
(You're supposed to know how to multiply fractions by whole numbers, so
I'm leaving out some steps. Do NOT go any farther until you understand
how I multiplied each fraction by 12, and got everything in the next line):
8 + 9K = 71
Subtract 8 from each side:
9K = 63
Divide each side by 9 :
K = 7
