The sum of two numbers is 30. the difference one the two numbers is 4

20+10 is 30 5x6 is 30

Step-by-step explanation:

so just add numbers to find 30

first number is 17 and second number is 13

Step-by-step explanation:

let the numbers are x and y

if their sum is 30 and difference is 4

then

x+y=30     1equation

x-y=4          2equation

add both the equations,

2x=34

x=17

then  

put the value of x in 1equation,

x+y=30

17+y=30

y=30-17

y=13

then,

first number is 17 and second number is 13
