5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6
7m-5 = 9 7m = 9+5 7m = 14 m = 2
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
7m + 12We've examined it carefully looking for an 'equals' sign ( = ), but we've beentotally unsuccessful. So we know that it can't be an equation.It must be an expression.

7x equals 3500
7m + 2 = 37 or 7m = 37 - 2 or 7m = 35 So m = 5

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!
-7m + 20 = -17m - 1010m = -30m = -3
