2(bx - 5) = 16 what’s does b and x equal?

To solve this problem you must apply the proccedure shown below:
 You have the following equation given in the problem above:
 -2(bx - 5) = 16
 When you solve for bx, you have:
 -2(bx - 5) = 16
 -2bx-10=16
 -2bx=26
 bx=26/-2
 bx=-13

 When you solve for b, you obtain:
 -2(bx - 5) = 16
 -2bx=26
 b=-(26/2x)

 When yoo solve for x:
 2bx=26
 x=-(26/2b)
