Answer 1

Значит так:
дано уравнение b-0.872b=32
b(1-0.872)=32
0.128 b=32

Answer 2

Sure! To solve the equation:

B - 0.872b = 32

We want to isolate the variable "b" on one side of the equation. To do that, we can start by adding 0.872b to both sides of the equation:

B - 0.872b + 0.872b = 32 + 0.872b

Simplifying the left-hand side:

B = 32 + 0.872b

Now, we want to isolate "b" on one side of the equation. We can do that by subtracting 32 from both sides of the equation:

B - 32 = 0.872b

Finally, we can divide both sides of the equation by 0.872 to solve for "b":

b = (B - 32) / 0.872

And that's the solution!
