Answer 1

Answer:

let the numbers be x,y

x+y=16

x-y=2

by adding the equations

2x=18

x=9

y=7

Answer 2

Answer:

9 and 7

Step-by-step explanation:

let the number be x and y.

given that,

X + Y = 16. (eq 1)

X - Y = 2. (eq 2)

by adding this equation.

We got,

2x = 18

it means, X = 9.

now put the value of X in any equation

X + Y = 16

9 + Y = 16

then, Y = 16 - 9 = 7
