Answer 1

Answer:

11

Step-by-step explanation:

If they are thinking same number than both the number must be equal...

=> 7x-14=4x+19

=> 3x=33

=> x=11

Answer 2

Answer:

x=11; number=63

Step-by-step explanation:

Since both Barry and Kathryn are thinking of the same number,

$7x-14=4x+19\\7x-4x=19+14\\3x=33\\x=\frac{33}{3} \\x=11$

Barry's number is

$7x-14=7(11)-14=77-14=63$

Kathryn's number is

$4x+19=4(11)+19=44+19=63$ ..........(Verified!)

Hope it helps!
