Answer:

n=11.5

Step-by-step explanation:

Given:

The two expressions are:

(ny+25.7)+(-45.2y+13.9)=(n-45.2)y+39.6

-33.7y+39.6

If the above 2 expressions are equivalent, then the coefficients of y should be equal for both the expressions.

The coefficient of y in the first expression is:

(n-45.2).

The coefficient of y in the second expression is:

-33.7.

Therefore,

n-45.2=-33.7\\n=-33.7+45.2=11.5
