Answer:
8 pieces.
Step-by-step explanation:
12 / 1.5
= 24 / 3
= 8.
3(12 - 2n) = 36
36 - 6n = 36
-6n = 0
n = 0 <== ur number
Answer: see image attached
y<x/2+6 is the yellowish area (with dashed boundary as that does not belong to the solution space)
x+3y>=12 is rearranged as y>=-x/3+4 and solutions correspond to the bluish shaded area (with solid line, due to the equal sign)
The solutions satisfying both inequalities are in the overlap area of the two.
