Answer 1

`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
`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`
