Get one x+y=3 to y=x+3 and plug it into x-y=1 and you get x-(x+3)=1. Destitute the x and solve. Once you get what x equals plug it to to either equation for the value of x and solve for y

X-y=1. ....> x=1+y
(1+y)+y =3
1+y+y =3
1+2y =3
2y=3-1=2 ....>y =2/2=1
Y=1
X-y=1
X-1=1. ....>x=1+1 =2

X=2. Y=1

UNO [17]

Answer:

Step-by-step explanation:

1 Escritura unida

Según la NGLE se unen las palabras que se interpretan como una unidad y en las que, por tanto, la marca de plural solo afecta al último elemento:[1]

el bajorrelieve, los bajorrelieves

la mediapunta, las mediapuntas

En un buen número de casos, el primer elemento puede seguir teniendo individualidad para parte de los hablantes y admitir la marca del plural. La Gramática admite algunos de esos casos, de modo que las dos formas son posibles, que se escribirán unidas o separadas según se dé ese plural o no:

el puercoespín, los puercoespines; el puerco espín, los puercos espines

el arcoíris, los arcoíris; el arco iris, los arcos iris

el medioambiente, los medioambientes; el medio ambiente, los medios ambientes.

el pavorreal, los pavorreales; el pavo real, los pavos reales

La Gramática prefiere, como norma general, la forma en una palabra.

The general form of rectangular hyperbola is,

$xy=c^2$

Where c is a constant.

Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .

Equation 2 represents an exponential function.

Equation 2 represents an cubic function.
