3. Anita and Boris are shooting at a target with a ball, each 50 times. One part of the target is painted yellow, and the other part is blue. For each hit on the target, a certain number of points is awarded, and if the target is missed, no points are awarded. Anita hit the yellow part 36 times and missed the target 2 times. Boris hit the blue part 6 times and missed the target twice as many times as Anita. At the end of the shooting, the teacher told them that they had scored a total of 716 points, and that Boris scored 4 points less than Anita. How many points does hitting the yellow part, and how many points does hitting the blue part of the target bring?
First method:

By multiplying the second equation by 2, we get the equation

$80 x + 12 y = 712$

$36 x + 12 y = 360$

From this, it is clear that the left sides differ by $44 x$, and the right sides by 352,

so $44 x = 352$

$x = 352 : 44$

$x = 8$. A hit in the yellow part of the target scores 8 points.

$6 y = 356 - 320$

$6 y = 36$

$y = 36 : 6$

$y = 6$. A hit in the blue part of the target scores 6 points.
