Answer:
b = 2/5 = 0.4
Step-by-step explanation:
We know that:
[tex]15 - \frac{6}{3*b} = 10[/tex]
We want to find the value of b, then we need to isolate b in one side of the equation.
First, let's subtract 15 in both sides of the equation so we get:
[tex]- \frac{6}{3*b} = 10 - 15 = -5[/tex]
Now we can multiply both sides by 3*b, so we get:
[tex]- 6 = -5*3*b = -15*b[/tex]
Now we can divide both sides by -15:
[tex]-6/-15 = b[/tex]
Then:
b = 6/15 = 2/5
b = 2/5 = 0.4
