Sum
two natural numbers is 10 and to
difference between them is 4. Find the
numbers.​

Answer 1

Answer:

sum : 7+3=10

difference : 7-3=4

step by step:

● x+y=10

x=10-y ------(1)

● x-y=4

y= -4+x --------(2)

from (1) and (2)

second no . x-y=4

(10-y)-y =4 put the values

10-2y=4

-2y= 4-10

-2y = -6

y = -6/-2

y= 3

1st no. x+y=10

x+4=10

x=10-4

x = 7

so the 2 numbers are 7 and 3
