Let the number of girls be x and the number of boys be y.

Given, total no. of participants is 15.

x + y = 15

Also, boys participants is 5 less than the number of girls participants

x = y – 5

We have two equations we will plot them and their intersection will give the required result.

x + y = 15 x = y – 5  Plotting these points on a graph and joining them, we get two straight lines.

From the graph, we can see that both lines intersect at (5, 10), hence solution to this pair is (5, 10).

no. of boys is 5 and no. of girls is 10
