Respuesta :
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
Solution:
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.
