∙ 12y ago7m + 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
7x equals 3500
Add 10 to each side: 7m = 49 so m = 7
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
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
5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6
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.
-7m + 20 = -17m - 1010m = -30m = -3
7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
That depends on the value you give to 'm'.
m = 8
7 - 14m

7m-5 = 9 7m = 9+5 7m = 14 m = 2
It is a linear equation in the single variable, m. It has the solution m = 0
