Question

the sum of two numbers is 19 and the difference is 7 what are the two numbers

Answer 1

Answer:

x=13

y=6 the answer for this question

Answer 2

Let the two numbers be x and y.

Given:

x + y = 19

x = 19 - y... (I)

and

x - y = 7

19 - y - y = 7 ( from I)

-2y = 7 - 19

y = - 12 / -2

y = 6

Putting the value of y in equation I, we have

x = 19 - 6

x = 13

Hence, the two numbers are 13 and 6.

Hope it helps.
