Using x to represent the larger number and y to represent the smaller number, do this:
x - y = 9
x = 1/2y + 20
(1/2y + 20) - y = 9
(1/2y - y) + 20 = 9
-1/2y + 20 = 9
         -  20  - 20
-1/2y = -11
Divide each side by -1/2 to find y
y = 22
Plug the y value into the first equation
x - 22 = 9
  + 22 + 22
x = 31

The larger number is 31 and the smaller number is 22

Large = 20+ 1/2 of small and,

Large-small =9 so if we put back the 9 to the small one will get the large number
Large=9+small

Now we can see that
20+small/2 =9+ small
20-9=small-small/2
11=half of small so small is 22

Large = 20 + 11=31

Si un rectángulo con perímetro de 74 pulgadas tiene un largo de 5 pies más que el ancho,
baherus [9]

Perímetro del rectángulo = 74 pulgadas

Deje que el ancho del rectángulo sea 'x'.

Entonces, la longitud de este rectángulo = x + 5

We know that :

\color{hotpink}\tt \: Perímetro  \: del \:  rectángulo =\color{plum} 2 × (l + b)

Lo que significa :

=\tt 2(x + x + 5) = 74

=\tt 2(2x + 5) = 74

=\tt 4x +10 = 74

=\tt 4x = 74 - 10

=\tt 4x = 64

=\tt x =  \frac{64}{4}

\color{plum} =\tt x = 16

Por lo tanto, el ancho de este rectángulo = 16 pulgadas

Entonces, la longitud de este rectángulo :

=\tt x + 5

= \tt16 + 5

\color{plum} =\tt 21 \: pulgadas

La longitud de este rectángulo = 21 pulgadas

<h2>Por lo tanto :</h2>

● Longitud del rectángulo = <em>21 pulgadas</em>

● Ancho del rectángulo = <em>16 pulgadas</em>
