Question

X+x+y+y=36 y (x)(y)=80

Answer 1

Respuesta: x=8 , x=10 ; y=8 y=10

Explicación paso a paso:

X+x+y+y=36

=2x+2y=36

(x)(y)=80

Despejamos "x"

x=−y+18

Sustituimos "x"

(-y+18)(y)=80

-y^2+18y=80

-y^2+18y-80=0

Factorizamos.

(-y+8)(y-10)=0

Igualamos los factores a cero.

-y+8=0

-y= -8

y= -8 / -1

y=8

y-10=0

y=10

Sustituimos "y"

x=−y+18

x= -8+18

x=10

x=-10+18

x=8
