Consider the equation and its solution. Negative 15 (x minus box) = 25. Negative 15 x + 30 = 25. Negative 15 x = negative 5. x = one-third. What number should be in the empty box? Negative 30 Negative 2 2 30

Answer 2

Answer:

  -2

Step-by-step explanation:

Between the first two steps we see ...

  $15(x-\boxed{^})=25\\\\15x+30=25$

Applying the distributive property to the first equation and comparing to the second, we see that ...

  $-15\boxed{^}=30\\\\\boxed{^}=\dfrac{30}{-15}=-2$

The number in the box should be -2.
