28 + (3x -2) + 28 = 6x
28+ (3x -3x -2) + 28 = 6x - 3x
28+ (-2) + 28 = 3x
28 - 2 + 28 = 3x
26 + 28 = 3x
54 = 3x
18 = x

Hello there!

<span>28 + (3x - 2) + 28 = 6x
</span>

Answer: x = 18
----------------------------------------------------------------------------------------------------------

Explanation: 


First, let's  combine like-terms.

28 + 28 = 56

Now, we have 56 + (3x - 2) = 6x 

Let's subtract 56 from each side to get rid of those parentheses.

56 + (3x - 2) = 6x 
-56                 -56

Now, we have 3x - 2 = 6x - 56

Let's add 2 to each side

3x - 2 = 6x - 56
+2              +2

3x = 6x - 54

Now, we will subtract 6x from each side

3x = 6x - 54
-6x   -6x

We now have -3x = -54

let's multply each side by -1 to make x a postive number.

-3x = -54
*-1     *-1

We have 3x = 54

Now, we must divide each side by 3 

3x = 54
--     ----
3      3

Our answer is x = 18

1. Los estudiantes de primer grado de la IE Miguel Grau son 184, si la relación entre los que usan anteojos y los que no usan es
Fudgin [204]

Answer:

69 estudiantes.

Step-by-step explanation:

Sabemos que el número total de estudiantes en primer grado es 184.

También sabemos que la relación entre los que usan anteojos y los que no es 3/5.

Esta relación es igual al cociente entre el número de estudiantes que usan anteojos y el número de estudiantes que no usan anteojos.

Si definimos las variables:

A = número de estudiantes que usa anteojos

B = número de estudiantes que no usa anteojos.

Tenemos la relación:

A/B = 3/5

podemos reescribir como:

A = (3/5)*B

Y también sabemos que el número total de estudiantes es 184, entonces tendríamos que:

A + B = 184.

Podemos aislar B en esta segunda ecuación para luego reemplazarlo en la primera.

Aislando B obtenemos:

B = 184 - A

Si reemplazamos esto en la otra ecuación obtenemos:

A = (3/5)*B

A = (3/5)*(184 - A)

Ahora podemos resolver esto para A.

A = (3/5)*184 - (3/5)*A

A + (3/5)*A = (3/5)*184

A*(1 + 3/5) = (3/5)*184

A*(5/5 + 3/5) = (3/5)*184

A*(8/5) = (3/5)*184

A = (5/8)*(3/5)*184

A = 69

Podemos concluir que 69 estudiantes usan anteojos.
