Answer:

x=7

y=8

(x+y)= 15

(x-y)= -1

Step-by-step explanation:

let x and y be the numbers

x + y = 15 ------ 1

2x - y = 6 ------ 2

add both equation 1 and 2

3x = 21

x = 21\3

x=7

subtitute 7 for x in equation 1

7 + y = 15

y = 15-7

y=8

The first number x = 7

The second number y = 8

thus x + y = 7 + 8 = 15

x - y = 7 - 8 = -1
