Define your variables:
X =
Y =
boxes.
boxes, and Ayan sold
Kay sold

Answer 1

Answer:

Kay sold 6 boxes and Ayan sold 19 boxes

Step-by-step explanation:

Let x be the number of boxes sold by Kay and

Let y be the number of boxes sold by Ayan

Then according to given statements, the equations will be:

$x+y = 25\ \ \ Eqn\ 1\\x = y-13\ \ \ Eqn\ 2$

Putting x = y-13 in equation 1

$y-13+y = 25\\2y-13=25\\2y=25+13\\2y = 38\\\frac{2y}{2} = \frac{38}{2}\\y = 19$

Putting y = 19 in equation 2

$x = 19-13 = 6$

So we get x=6 and y=19

Hence,

Kay sold 6 boxes and Ayan sold 19 boxes
