M + 20 = 9
u need to subtract 20 from both sides because u want to isolate m
m + 20 = 9
m + 20 - 20 = 9 - 20
m = - 11

Answer:
Step-by-step explanation:
The area of solutions of the first inequality lies above an orange straight line.
The area of solutions of the second inequality lies below a blue straight line.
These areas are crossed in the yellow field.
The green field does not meet a condition of the second inequality and therefore does not enter the area of the solution of a system of inequalities
