in The Multiplication Puzzle we took 3x as the played hand and 21 as the result on the board.
Doing the same with 5x + 2 = 3x + 8 we would take 5x + 2 as the played hand
and 3x + 8 as the result on the board.
What does an x piece played on the board look like?
In this case x is declared as 3, so take three black counters and hide them in a box and label the box with an x
Counters in box Close box Label box
Now as the wildbox,
, contains three black counters make a negative wildbox that contains three white counters, . Removing the counters gives three pairs of
in other words Zero.So the pair
is another form of Zero and can be removed.TIP In solving this type of puzzle always play cards that will remove wildboxes from the board.
We set up the board by playing a wildbox,
, for the wildcard 
Having put three black counters in the wildbox this declares the wildcard as a Three.

Swap the hand for the other one that gives the same result which gives the puzzle to play
