Question

what is the sum of two number s is 19 and their differences is 5

Answer 1

Sum Of 12 And 7 is 19

Whereas There Differance Is 12-7=5

Answer 2

Step-by-step explanation:

So first we are told two numbers add to 19 :a+b=19

And they subtract to 5 :a−b=5

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

(1) + (2): (a+b)+(a−b)=19+5

2a=24a=12

In (1):12+b=19b=7

So the two numbers are 12 and 7..
