Form the pair of linear equations in the following problems,and find their solutions graphically.
$10$ students of Class $X$ took part in a Mathematics quiz. If the number of girls is $4$ more than the number of boys,find the number of boys and girls who took part in the quiz.

(N/A) Let the number of girls be $x$ and the number of boys be $y$.
According to the question,the algebraic representation is:
$x + y = 10$
$x - y = 4$
For $x + y = 10$,we have $x = 10 - y$:

$x$	$5$	$4$	$6$
$y$	$5$	$6$	$4$

For $x - y = 4$,we have $x = 4 + y$:

$x$	$5$	$4$	$3$
$y$	$1$	$0$	$-1$

By plotting these points on a graph,we observe that the lines intersect at the point $(7, 3)$.
Therefore,the number of girls is $7$ and the number of boys is $3$.
