Question

the sum of two natural numbers is 25 of their difference is 7. find the numbers

Answer 1

Let the number be x
thus
one no is x
second no is x+7

therefore x+x+7=25
2x+7=25
2x=25-7
2x=18
x=18÷2
x=9
so one no is 9
another 9+7
16

Answer 2

let the no be x and y
according to question
x+y=25. -eq1
x-y= 7. -eq2
now add 1+2 equation and u will find
x+x=25+7
2x=32
x=16
so y =25-16=9
x=16, y=9 Answer
