Question

The sum of 2 numbers is 15 and their qoutient is 2

Answer 1

Given:

• x + y = 15
• x/y = 2

Let’s simplify the second equation to find out the value of x.

• x/y = 2
• x = 2y

Now, let’s substitute the value of x into the first equation.

• x + y = 15
• 2y + y = 15
• 3y = 15
• y = 5

Now, let’s substitute the value of y into the simplified second equation.

• x = 2y
• x = 2(5)
• x = 10

Hence, the value of x and y are 5 and 10 respectively.

Answer 2

x + y = 15------(1)

x/y = 2------(2)

y = 15 - x

put this value in eq 2

x/(15-x) = 2

x = 2 (15 - x)

x = 30 - 2x

2x + x = 30

3x = 30

x = 10

y= 15 - x

y = 15 - 10

y = 5
