How would you work out this problem?

I know the answer is 10. But how would you get to that point? I want to know how to work out this problem:

b/5 + 8=b.

Thanks.


Answers:    bring back the b's together by subtracting b/5 from each side and you seize (4/5)b = 8.

divide by 4/5 and you get b= 8/ (.8) = 10
Multiply both sides by 5:
b + 40 = 5b

Subtract b from both sides:
4b = 40

Divide by 4:
b = 10.
1) multiply both sides by 5:
b+40=5b

2) return with all the b's together:
40=4b

3) divide by 4:
10=b
b/5 + 8 = b ==> b/5 - b = -8 ==> b x 1/5 - b = -8

(b x 1/5 - b) 5 = (-8) 5 (multiplied both side by 5 to go and get rid of fraction)

b - 5b = -40

==> 4b = 40 ==> 4b/4 = 40/4

==> b = 10
