Answer 1

Answer:

x+y=16

x-y=4

2x=20

x=20/2

x=10

substitute x=10 in x+y=16

10+y=16

y=16-10

y=6

therefore x=10

y=6

Answer 2

Answer:

first number is 10.

Second number is 6.

Step-by-step explanation:

,Suppose,First number = X

second number = y

x+y=16......1

x-y=4.......2

add equation 1 and 2

x+y=16 + x-y=4

2x=20

x=20/2

x=10

put x=10 in equation 1

x+y=16

10+y=16

y=16-10

y=6
