Question

(x-3) : 3 + 20 = 4 ( al cuadrado) + 8 Alguien la save! con verificacion pliss

Answer 1

(x - 3) / 3 + 20 = 4² + 8

(x - 3) + 3 * 20
------------------- = (4)² + 8
          3

(x - 3) + 60
--------------- = 16 + 8
       3

(x + 57)/3 = 24

x + 57 = 24 * 3

x + 57 = 72

x = 72 - 57

x = 15

Solución : 

x = 15

VERIFICAMOS : 

(15 - 3)/3 + 20 = (4)² + 8

12/3 + 20 = 16 + 8

4 + 20 = 24

24 = 24

Listo. 

Answer 2

Resolver.

(x - 3)/3 + 20 = 4² + 8
(x - 3)/3 + 20 = 16 + 8
(x - 3)/3 = 24 - 20
(x - 3 )/3 = 4
x - 3 = 4 * 3
x - 3 = 12
x = 12 + 3
x = 15

Respuesta.
x = 15
