Sagot :

Kamilidn
x - 2-point field goals
y - 1-points field goals

2x + y = 44
x + y = 30

2x = 44 - y
y = 30 - x

2x = 44 - y
y = 30 - (22 - 1/2y)

2x = 44 - y
y = 30 - 22 + 1/2y

2x = 44 - y
1/2y = 8

2x = 44 - y
y = 16

2x = 44 - 16
y = 16

2x = 28
y = 16

x = 14
y = 16 

x + y = 30
14 + 16 = 30
L = R

2x + y = 44
28 + 16 = 44
44 = 44
L = R
