Make sure that whatever you do to one side, you must also do to the other. For each of the given values of n, you must find the corresponding value of M.
M + 3n = 7
For n = -2:
M + 3(-2) = 7
M + (-6) = 7
M - 6 = 7
M - 6 + 6 = 7 + 6 | adding 6 to both sides
M = 13
For n = 0:
M + 3(0) = 7
M + 0 = 7
M = 7
For n = 1:
M + 3(1) = 7
M + 3 = 7
M + 3 - 3 = 7 - 3 | subtracting 3 from both sides
M = 4
Hope this helps! :)

Answer:
Step-by-step explanation:
No
Answer:
13a: Measure of angle 1 is 120 degrees
13b: Angle 2 is 60 degrees
Step-by-step explanation:
Angle 1 is alternate exterior (so in a parallel pair they are equal) to the angle on line m given as 120 deg.
Angle 2 is 180 minus 120= 60 Sum of the two angles must equal 180.
