x - y = 5

x.y = 3.36

[tex](x-y)^2=5^2[/tex]

[tex] x^{2} -2xy + y^{2} =25[/tex]

[tex] x^{2} + y^{2}=25+6.72=31,72 [/tex]

[tex](x+y)^2= x^{2} +2xy+ y^{2} =31,72 + 6,72 = 38,44[/tex]

[tex] \sqrt{(x+y)^2}= \sqrt{38,44} [/tex]

x+y= 6,2
 and we know that x - y= 5

x+y+x-y=6,2 + 5
2x=11,2
x=5,6

so then y=0,6

Answer:

x= 5,6
y= 0,6
