Osman has bought a total of five jerseys for Harimau Team The steps to determine
and Kancil Team. What are the possible numbers of jerseys the possible solutions
that can be bought for each team? of linear equations in
two variables:

Let the number of jerseys for Harimau Team = x Choose a value for one
of the variables.
and the number of jerseys for Kancil Team = y
Thus, x + y = 5 Substitute the value
into the linear equation.
Number of jerseys for Number of jerseys for
Harimau Team Kancil Team
Solve the equation to
x = 1 y = 4 find the value of the
x = 2 y = 3 other variable.

x = 3 y = 2 CHAPTER
x = 4 y = 1

Besides the pairs of solutions listed above, is there any other pair of solutions for the number of
jerseys that Osman bought? Discuss.
