X + y = 120000
0.15x - 0.10y = 5500
Multiply both sides of bottom by 100 to remove decimals
x + y = 120000
15x - 10y = 550000
Multiply both sides of top by 10
10x + 10y = 1200000
15x - 10y = 550000
Add the two
25x = 1750000
x = 70000

Answer:
b = 3c
B = 4c
Step-by-step explanation:
2b + B = 8c
B - b = 2c
_____________ (-)
2b + B - B + b = 8c - 2c
3b = 6c
b = 6c : 3
b = 2c
B = 2c + b
= 2c + 2c
= 4c
