One number is 7 more than another number, and their sum is 13. find the two numbers

10 and 3

Step-by-step explanation:

let the first number be x and the second be y

x=y+7i

their sum is 13

x+y=13ii

substituting for x in ii

y+7+y=13

collecting like terms

2y=13-7

2y=6

y=3

recall ii and substitute for y

x+y=13

x+3=13

collecting like terms

x=10
