Question

deviding 250 into two parts so that 3 times the first part and 5 times the second part together make 950​

Answer 1

Answer:

x= 300

y = -50

Step-by-step explanation:

Lets take the two numbers to be x and y

So, 250 =x + y

Now,

250 - y = x               - 1

We also know that,

3x + 5y = 950

In this equation, substitute 1

3(250 - y) - y = 950

750 - 4y = 950

-4y = 200

y = 200/4 = -50

now,

250 - (-50) = x

x = 300

Answer 2

Let x and y be the first part and second part respectively.

By question, we get

x+y=250

=> x= 250- y _______1

We know that,

3x+5y= 950

In this equation, substitude equation 1

3x+5y=950

=> 3(250-y)+ 5y= 950

=>750-3y+5y=950

=>-3y+5y= 950-750

=>2y= 200

=>y=200/2

=100

therefore, y=100

Now,

x=250-y

=250-100

= 150

therefore, x = 150

Hence, the first part , x= 150 and the second part , y= 100
