observe as seguintes situações e sua representação em linguagem matematica dois numeros x e y são tais 2x y=6 x-y=3
agasfer [191]

Answer:

The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"

Step-by-step explanation:

Given values:

2xy =6.....(a)\\\\x-y= 3.....(b)\\\\

After solve equation (a) we get

\ equation: \\\\2xy= 6\\\\xy =\frac{6}{2} \\\\xy = 3.....(x)\\\\

After solve equation (b) we get

\ equation: \\\\x-y =3\\\\x= 3+y....(x1)\\

put the value of x in to equation (x)

(3+y)y = 3\\

y^2+3y-3=0\\\\\ compare \ the \ value \ with \ ay^2+by+c=0\\a= 1\\b=3\\c=-3\\\ Formula: \\y= \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\y= \frac{-3\pm \sqrt{9+12}}{2}\\y= \frac{-3\pm \sqrt{21}}{2}\\

The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29
