Question

8) Hallar “x” en: 7x – 57 = 2x + 73

Answer 1

Respuesta:

$\large\boxed{x = 26}$

7x – 57 = 2x + 73

7x -2x = 73 + 57

5x = 130

x = 130/5

x = 26

Comprobamos:

7x – 57 = 2x + 73

7(26) - 57 = 2(26) + 73

       125  = 125

Answer 2

respuesta

x = 26

$7x - 57 + 57 = 2x + 73 + 57 \\ 7x = 2x + 130 \\ 5x = 130 \\ \\ \frac{5x}{5} = \frac{130}{5}$
