The LCM of 7m-21 and 14m-42 is 14m-42. Since 14m-42 is a multiple of 7m-21, it is also the least common multiple (LCM) of the two expressions.
7m-5 = 9 7m = 9+5 7m = 14 m = 2
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
7x equals 3500
7m + 2 = 37 or 7m = 37 - 2 or 7m = 35 So m = 5
700

7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
-7m + 20 = -17m - 1010m = -30m = -3
Oh, dude, let me break it down for you. So, you plug in n as 6 and m as 4, and you get 12 over 6 plus 7 times 4. That simplifies to 2 plus 28, which equals 30. So, the answer is 30. Easy peasy, lemon squeezy!
Add 10 to each side: 7m = 49 so m = 7
