Answer 1

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,

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