Question

The sum of two numbers is 19 and their difference is 7 . Find the numbers

Answer 1

Answer:

13

Step-by-step explanation:

Let x be the number

x+7=19

x=19-7

x=13

Answer 2

ANSWER: let the numbers be a and b

then we are told

a+b=19

a-b=7

adding these two equations we get

2a=26

subtracting the second from the first we get

2b=12

dividing each of these equations by 2 we get

a = 13

b = 6
