Answer 1

x =-1

Explanation:

`-2(bx - 5) = 16\\b = 3\\x = ?\\-2(3x -5)=16\\\\\mathrm{Divide\:both\:sides\:by\:}-2\\(-2\left(3x-5\right))/(-2)=(16)/(-2)\\\\Simplify\\3x-5=-8\\\\\mathrm{Add\:}5\mathrm{\:to\:both\:sides}\\3x-5+5=-8+5\\\\Simplify\\3x=-3\\\\\mathrm{Divide\:both\:sides\:by\:}3\\(3x)/(3)=(-3)/(3)\\\\Simplify\\x =-1`
