Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>

Answer:
The original cost of Car at the time of purchased = 20500 unit
Step-by-step explanation:
According to question ,
Mr. Kork selling cost of his Car = 8400 unit
And Selling cost is 200 more than two fifths of the purchased cost of Car .
Let the Purchased cost of car = X unit
So, AS per question
200 +
× x = 8400
Or,
× x = 8400 - 200
i.e
× x = 8200
So , x = 8200 ×
∴ x = 4100 × 5 = 20500 unit
Hence The original cost of Car at the time of purchased = 20500 unit Answer
