7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
Add 10 to each side: 7m = 49 so m = 7
7x equals 3500
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!
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
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 + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
-7m + 20 = -17m - 1010m = -30m = -3
4m + 3m = 180 7m = 180 m = 25 5/7
7 - 14m
Add 10 to each side: 7m = 49 so m = 7
The answer is -369.

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.
