Answer:
The numbers are 20 and 10.
Step-by-step explanation:
Let's say these teo numbers are x and y.
The sum of two numbers is 30
x + y = 30
Isolate y
y = 30 - x
Their quotient is 2
plug the newfound y value in the second equation.
x / y = 2
[tex]\frac{x}{30-x} = 2[/tex]
multiply both sides by (30 - x) to get rid of the fraction.
x = 2(30 - x)
x = 60 - 2x
x + 2x = 60 + 2x
3x = 60
dividie both sides by 3
x = 20
find y
y = 30 - x
y = 30 - 20 = 10
y = 10
The numbers are 20 and 10.
Answer:
10 and 20.
Step-by-step explanation:
x + y = 30
x/y = 2
x = 2y so substituting in the first equation:
2y + y = 30
y = 10
and x + y =30
so x + 10 = 30 giving x = 20.
