If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
-7m + 20 = -17m - 1010m = -30m = -3
That depends on the value you give to 'm'.
m = 8

If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
7m + 2 = 37 or 7m = 37 - 2 or 7m = 35 So m = 5
7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
-7m + 20 = -17m - 1010m = -30m = -3
That depends on the value you give to 'm'.
m = 8
7 - 14m
12/n+7m=30 12/6=2 + 7x4=28
Since 14m - 42 is a multiple of 7m - 21, it is automatically the LCM of this problem.
7m-5 = 9 7m = 9+5 7m = 14 m = 2
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.
