Answer:
( 7,-1)
Step-by-step explanation:
a.. rs 7000
Because 15×1000=15000 it is SP when selling 1000units in the rate of Rs 15/unit& 8×1000=8000 this is cp when buying 1000 units in the rate of Rs 8/unit.
So,by formula of profit,
Rs (15000-8000)=Rs7000
x = -1
y = 6x - 14 y= -8x
6x-14 = -8x
- 6x
-14 = 14x
300.
