b/5=1.
By multiplying each side by 5 we get another equation: b=5 (which is the solution for finding b).
We can then get another equation by subtracting 5 from each side: b-5=0.
We can get another equation from the original one by dividing both sides by b: ⅕=1/b, which can also be written 1/b=⅕.
And we can add the same constant to each side of the original equation:
b/5+2=3; or we can multiply both sides by the same constant: 3b/5=3.
We can combine adding and multiplying: 3b/5+6=9.
There are many equations we can write starting with the original one. But they all have one thing in common: b=5, that is, b always has the value of 5 in every equation we derive.
