<u>First Solution</u>
        -2x + y = 1
-2x + 2x + y = 1 + 2x
                 y = 1 + 2x

<u>Second Solution</u>
     -2x + y = 1
-2x + y - y = 1 - y
           <u>-2x</u> = <u>1 - y</u>
            -2       -2
              x = -0.5 + 0.5y
0.5 + x - x = -0.5 + 0.5 - x + 0.5y
           0.5 = -x + 0.5y
 -0.5y - 0.5 = -x + 0.5y - 0.5y - 0.5
   2 · (-0.5y) = 2(-x - 0.5)
                y = -2x - 1

<u>Third Solution</u>
             -2x + y = 1
        -2x + y - 1 = 1 - 1
        -2x + y - 1 = 0
-2x + 2x + y - 1 = 2x
                 y - 1 = 2x
           y - 1 + 1 = 2x + 1
                      y = 2x + 1

astra-53 [7]
The equation is already solved for the variable t To solve for any other variable simply rearrange theequation to have the indicated variable on one sideof the equals sign and everything else on the other. For example, to solve for a: t=an+b       subtract b from both sidest-b = an      divide both sides by n(t-b)/n = a Or:  a = (t-b)/n Work in the same manner to solve for either b or n: b = t-an n = (t-b)/a

El agua de una psicina alcanza 250 cm de altura. Si la estatura de pablo es 1520 mm dentro de la piscina sin que el agua lo cubr
Andrews [41]

Respuesta:

Pablo se cubrirá de agua si se para en la piscina

Explicación paso a paso:

El nivel del agua en la piscina = 250cm.

Altura de Pablo = 1520 mm

Para saber si pablo podría pararse en la piscina sin estar cubierto de agua, necesitamos determinar la altura de Pablo en centímetros.

Convertir la altura de Pablo de milímetro a centímetro;

1 mm hasta 0,1 cm

1520 mm = (1520 * 0,1) = 152 cm

Por lo tanto, pablo mide 152 cm.

Esto significa que la altura del agua en la piscina es mayor que la altura de Pablo y esto lo cubrirá el agua si se para en la piscina.
