Answer 1

Answer:

Answer is 7

Step-by-step explanation:

x+y=30

x-y=16

add both equations, we get

2x=46

x=23

23+y=30

y=30-23

=7

7 is smaller than 23

So, answer is 7

Answer 2

Answer:

The smaller number is 4

Step-by-step explanation:

Let the sum of two number x+y =30

the difference between these two numbers is x-y=16

adding above eqution

then we will get the value of x 26

now putting value 26 to equation 1

x+y=30

26+y=30

y=30-26

y=4
