:
Let x = no. of beepers
then
3x = no. of watches
:
23.46x + 27.98(3x) = 537
23.46x + 83.94x = 537
107.40x = 537
x =
x = 5 beeper
and
3*5 = 15 watches

You can check solution in the original equation
You can put this solution on YOUR website! let w and b be the number of watches and beepers respectively
:
27.98w+23.46b=537..eq 1
w=3b...............eq 2
:
take w's value in eq 2 and plug it into eq 1
;
27.98(3b)+23.46b=537
:
83.94b+23.46b=537
:
107.40b=537
