Respuesta :
X is the first number
Y is the second number
X+6 = 1/2Y
X+Y = 21
solving both equations will give you
X= 3 and Y =18
Y is the second number

Answer:
x = 11 ; y =10
Step-by-step explanation:
Hi, to find the numbers you have to write two equations,using the information given:
First equation
- X = 6 + 1/2y
Second equation
- X + Y = 21
So, substituting equation 1 in to the 2nd equation:
(6 + 1/2Y ) + Y =21
1/2Y +Y = 21 -6
3/2 Y =15
Y=12 /(3/2)
Y= 10
Finally,substituting the value of “Y” in the first equation
X +Y =21
X + 10=21
X= 21-10
X= 11
In conclusion, the answer is:
X=11 ; Y=10
