Answer:

10 and 19

Step-by-step explanation:

In Algebra, an even number = 2x, because anything multiplied by 2 is even.

There are two numbers in the question, I'll define the first one as 2x
the other number is 1 less than twice of the first, so I'm going to define it in algebra as 2(2x) - 1, which is just 4x - 1
the square of the first is $4x^2$
the square of the second is $16x^2-8x+1$
add them together: $20x^2-8x+1$
this equation = 461, so $20x^2-8x+1 = 461$
simplify to $20x^2-8x-460 = 0$
I wont explain how to solve this here, since it is very complicated, if you don't know search up solving quadratics.
the solutions are 5 or -4.6, it cannot be -4.6 since the question says positive, so the solution for x = 5
substitute x into our equations for the two numbers in steps 1 and 2
the first number = 10, the second = 19
