Answer:
x=2
y=3
Step-by-step explanation:
y=−2x+7
y=5x−7
Set the two equations equal since they are both equal to y
−2x+7
=5x−7
Add 2x to each side
-2x+7+2x = 5x-7+2x
7 = 7x-7
Add 7 to each side
7+7 = 7x-7+7
14 =7x
Divide by 7
14/7 = 7x/7
2 =x
Now find 7
y = 5x-7
y = 5(2) -7
y = 10-7
y = 3

Answer:
10500 rupees
Step-by-step explanation:
So 50 bags 300 per pack so
300*50= 15000
15000 is what he spent on the 50 bags of rice
So he spent 500 rupees on transportation
15000 + 500 = 15500 total spent which is not needed but extra information
30% loss is 30% of 15000 so
30% of 15000 = 4500
15000 - 4500 = 10500 rupees
