Question

5.
Se sabe que m @ n = 3m + 4m.
Halla x si (x + 1) @ 3x = 93.​

Answer 1

Respuesta:

x = 6

Explicación paso a paso:

m @ n = 3m + 4m.

Halla x

(x + 1) @ 3x = 93.

(x + 1) @ 3x  = 3(x + 1) + 4(3x) = 93

⇒

3(x + 1) + 4(3x) = 93x

3x + 3 + 12x = 93

15x = 93 - 3

15x = 90

x = 90/15

x = 6
