Answer:

$\Large \boxed{\sf 15 \ and \ 5}$

Explanation:

Let the first number be x.

Let the second number be y.

x is 3 times y.

Difference of x and y is 10.

x=3y

x-y=10

Put x as 3y in the second equation.

3y-y=10

Combine like terms.

2y=10

Divide both sides by 2.

y=5

Plug y as 5 in the first equation.

x=3(5)

Multiply.

x=15

The two numbers are 15 and 5.
