$Solution, 25-5x=80\quad :\quad x=-11$

$Steps:$

$\mathrm{Subtract\:}25\mathrm{\:from\:both\:sides}, 25-5x-25=80-25$

$\mathrm{Simplify},-5x=55$

$\mathrm{Divide\:both\:sides\:by\:}-5,\frac{-5x}{-5}=\frac{55}{-5}$

$Simplify, x=-11$

The correct answer is <u><em>B. -11</em></u>

Hope this helps!!!
