Answer:

n=11.5

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
should be equal for both the expressions.

The coefficient of
in the first expression is:

(n-45.2) .

The coefficient of
in the second expression is:

-33.7 .

Therefore,

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