The number of old beta and VHS tapes is 10 and 7 respectively.

<h3>Solving Simultaneous equations</h3>

Let the number of Beta and VHS tapes be x and y respectively;

Hence;

  • x + y = 17

  • x - y = 3

Subtract the equations to obtain y;

  • 2y = 14

y = 7

Substitute y= 7 into equation 1 to obtain x;

  • x + 7 = 17

  • x = 17-7

x = 10.
