Do you mean: m/3 - 7 > 11 Or, m/(3-7) > 11? I'll solve both.
1. m/3 - 7 > 11
First: eliminate the fraction - multiply the denominator with each term...
(3)(m/3) - (3)(7) > (3)(11)
Sec: cross cancel "like" terms & combine the rest...
m - 21 > 33
Third: isolate "m" on one side - add 21 with both sides...
m - 21 + 21 > 33 + 21
m > 54
2. m/(3-7) > 11
First: combine "like" terms in the denominator...
m/(-4) > 11
- m/4 > 11
Sec: eliminate the fraction - multiply the denominator with both sides...
(4)(- m/4) > (4)(11)
*Cross cancel "like" terms & combine the rest...
- m > 44
Third: rule - the variable "m" can't be negative > change the signs...
m > - 44

treat the > as an =:
m/3 - 7 > 11
m/3 - 7 + 7 > 11 + 7
m/3 > 18
m/3 * 3 > 18 * 3
m > 54
The thing to keep in mind with inequalities is that if you multiply or divide by a negative number, remember to switch the inequality (from > to < for example)
Hope this helps! :)

m/3-7>11
Multiply both sides by 3 to get rid of the fractions:
m-21>33
Add 21 from both sides:
m>54
Check:
54/3-7=11
18-7=11
11=11

m < -44

m>-44 this is a guess this question stinks
