Question

Sistema de equações fracionarias
x/2y=3
x=2+4y

Answer 1

x    =   3   
2y                passe o 2y multiplicando:         x = 3(2y)
x= 6y
x= 2+4y
6y=2+4y
6y-4y=2
2y=2
y= 2/2 = 1
y=1
x=2+4y
x=2+4(1)
x= 6
agora avalie a minha resposta...

Answer 2

 x/2y = 3
     x = 3.2y
                  x = 6y          (1)
                  x = 2 + 4y    (2)

                  x = x
                  6y = 2 + 4y
                  6y - 4y = 2
                         2y = 2
                           y = 2/2
                                             y = 1
             y em (1)
                   x = 6.1
                                             x = 6
                                                              SOLUÇÃO SISTEMA
                                                                       x = 6
                                                                        y = 1
