Answer:

4 and 7

Step-by-step explanation:

let's call the first number 'x' and the second number 'y'

so from the question we obtain two equations:

2x+y=15 ..... equation 1 and

x+y=11 .........equation 2

rearranging equation 2

y=11-x

now let's substitute it to equation 1

2x+11-x=15

x=15-11

x=4

now solving for y(let's take equation 2)

4+y=11

y=11-4

y=7
