Answer:

(-6,-5)

Step-by-step explanation:

X+y=-11

solve for x

x=-11-y

substiute x value into 2nd equation

2x-3y=3

2(-11-y)-3y=3

-22-2y-3y=3

-5y=25

y=-5

substitute -5 for y in either equation to find x

x+y=-11

x+-5=-11

x=-6

Mr.kork sold his car for 8400. This was 200 more than two fifths of what he had paid for the car originally. How much had Mr.kor

prisoha [69]

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 + $\frac{2}{5}$ × x = 8400

Or, $\frac{2}{5}$ × x = 8400 - 200

i.e $\frac{2}{5}$ × x = 8200

So , x = 8200 × $\frac{5}{2}$

∴ x = 4100 × 5 = 20500 unit

Hence The original cost of Car at the time of purchased = 20500 unit Answer
