Anumber is 6 greater than 1/2 another number. if the sum of the numbers is 21, find the numbers

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

Second equation

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
