Answer:

Step-by-step explanation:

let x>y

x+2y=11

x=11-2y

xy=12

(11-2y)y=12

11 y-2 y^2=12

2 y^2-11 y+12=0

2y²-8y-3y+12=0

2y(y-4)-3(y-4)=0

(y-4)(2y-3)=0

y=4,3/2

Answer:

8 and 3/2

Step-by-step explanation:

Let m and n be the two numbers. Then:

2m+n=11

n=11-2m

m(11-2m)=12

11m-2m²=12

2m²-11m+12=0

(2m-3)(m-4)=0

m=3/2 or 4

Since 11-2(4)=3, then m must be 3/2, and n must be 8. ☺☺☺☺
