Answer:
m=8
Explanation:
 11-m=51-6m
You put the like terms together first so it will be:
 6m-m=51-11 
because when the numbers cross the '=' sign the signs change so -6 becomes +6m which is the same as 6m then +11 becomes -11. Then you solve:
 =6m-m=51-11
 =5m=40
Divide each side by 5 so that you can be left with the value of m
 =5m÷5=40÷5
 =m=8
