the difference between two numbers is 7. there sum is 25. find the numbers
a-b=7 , a=7+b
a+b=25
(7+b)+b=25 (Becouse a=7+b)
7+2b=25
2b=25-7
2b=18 Divided with
b=(18/2)=9
a=7+b=7+9=16
a=16 , b=9
a-b=16-9=7
a+b=16+9=25
a+b=25
(7+b)+b=25 (Becouse a=7+b)
7+2b=25
2b=25-7
2b=18 Divided with
b=(18/2)=9
a=7+b=7+9=16
a=16 , b=9
a-b=16-9=7
a+b=16+9=25
