Question

what is the 2 numbers of 19 and the diffrence is 1

Answer 1

Answer:

So first we are told two numbers add to 19:

a+b=19 ---(1)

And they subtract to 5:

a−b=5 ---(2)

These are two simultaneous equation and can be solved by elimination:

(1) + (2):

(a+b) + (a−b) = 19 + 5

2a= 24

a=12

In (1):

12+b=19

b=7

So the two numbers are 12 and 7.
