Answer:
One number is and the other number is
Step-by-step explanation:
Let x be the smaller number and y be the bigger number.
x = x
y = 5x
6x + 3y = 3
6x + (3 * 5x) = 3
6x + 15x = 3
(÷3)
2x + 5x = 1
7x = 1
x =
6x + 3y = 3
6() + 3y = 3
+ 3y = 3
3y = 3 -
3y =
Divide both sides by 3 to get 1y:
y =
So one number is and the other number is

12y > 10 ( divide both sides by 12 )
y > , that is
y >
