Answer:


Step-by-step explanation:
Nathan's score is 11 less than 2 times Zac's score.
Let Z points be Zac's score and N points be Natan's score. then
2 times Zac's score = 2Z
11 less than 2 times Zac's score = 2Z -11
So, N = 2Z - 11
1. If Z=6, then 
2. If Z=7, then 
3. If Z=8, then 
4. If Z=9, then 
Thus, four other possibilities are

Solve for m by simplifying both sides of the equation, then isolating the variable.
m = -2.5
