Respuesta:
x + y = 4
Explicación paso a paso:
[tex]\frac{x}{2}+4=x[/tex]
[tex]\frac{x+8}{2}=x[/tex]
x + 8 = 2x
x = 8
[tex]\frac{y}{2}-2=y[/tex]
[tex]\frac{y-4}{2}=y[/tex]
y - 4 = 2y
y = - 4
x + y = 8 + ( - 4 ) = 8 - 4 = 4
[tex] \red{ \boxed{ \large \boxed{x = 8} } } [/tex]
[tex] \blue{ \boxed{ \large \boxed{y = - 4} } } [/tex]
[tex]\green{ \boxed{ \large \boxed{x+y=(8)+(-4)=8-4=4} } } [/tex]
[tex] \frac{x}{2} + 4 = x \\ 1(x) + 2(4) = 2(x) \\ x + 8 = 2x \\ x - 2x = - 8 \\ - x = - 8 \\ x = 8[/tex]
[tex] \frac{y}{2} - 2 = y \\ 1(y) - 2(2) = 2(y) \\ y - 4 = 2y \\ y - 2y = + 4 \\ - y = + 4 \\ y = - 4[/tex]
