anonymous · Answer

You can estimate by approximating the numbers, the equation is about the same as b/8 = -2, so the answer would be about -16 if you multiply by 8 on both sides.

anonymous · Answer

is that it?

anonymous · Answer

The solution is found by multiplying by 7.8 on both sides:

b = -2.15 * 7.8 = -16.77

anonymous · Answer

So the answer is reasonable because it's "pretty close" to -16.
