Question

{x+y=3 , 2y+8=x} método de igualacion AYUDAA​

Answer 1

[tex]x + y = 3 \\ 2y + 8 = x[/tex]

[tex]x = - y + 3 \\ x=2y + 8[/tex]

[tex] - y + 3 = 2y + 8[/tex]

[tex]3 - 8 = 2y + y[/tex]

[tex] - 5 = 3y[/tex]

[tex] - \frac{5}{3} = y[/tex]

[tex]x + ( - \frac{5 }{3} ) = 3[/tex]

[tex]x - \frac{5}{3} = 3[/tex]

[tex]x = 3 + \frac{5}{3} [/tex]

[tex]x = \frac{14}{3} [/tex]
