Solve 11b+62b+b=4b+53b3b for b.
10b+6= 2
___6_6
10b=4
Book says answer is 2/5.
I do not see how the problems comes down to this answer.

11b+62b+b=4b+53b3b
10b + 6 = 2
10b = 4
b = 4 / 10
b = 2/5
When you divide a negative and a postive, the answer is negative. So  negative 4 divided by positive 10 = 4/10 = 2/5
