S=2d
4s+3d=300000-80000
4s+3d=220000, now using s=2d in this equation you get:
4(2d)+3d=220000
8d+3d=220000
11d=220000
d=20000
So each daughter gets 20000 and each son gets 40000.
Answer:
If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent.
Step-by-step explanation:
t-19/7

7t -133
7t = 133
133/7 = 19
t = 19
