11-19m=-16m-16
move -16m to the other side
sign changes from -16m to +16m
11-19m+16m =-16m+16m-16 ( combine like terms)
11-19m+16m=-16
11-3m=-16
move 11 to the other side
sign changes from +11 to -11
11-11-3m=-16-11
-3m=-16-11
-3m=-27
divide both sides by -3 to get +m and by itself
-3m/-3=-27/-3
m=9
Check solution by using substitution method
11-19m=-16m-16
11-19(9)=-16(9)-16
11-171=-144-16
-160=-160
Answer:
m=9
