Answer

Answer:

C. 8

Explanation:

Step1: Reorganizar la ecuación

Comenzamos con $120 + 10x=25x$. Restamos $10x$ de ambos lados: $120=25x - 10x$.

Step2: Simplificar el lado derecho

$25x-10x = 15x$, entonces la ecuación es $120 = 15x$.

Step3: Resolver para $x$

Dividimos ambos lados por 15: $x=\frac{120}{15}=8$.
