Question

If 15-6/3b =10, then b=

Answer 1

Answer:

b = 2/5 = 0.4

Step-by-step explanation:

We know that:

$15 - \frac{6}{3*b} = 10$

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:

$- \frac{6}{3*b} = 10 - 15 = -5$

Now we can multiply both sides by 3*b, so we get:

$- 6 = -5*3*b = -15*b$

Now we can divide both sides by -15:

$-6/-15 = b$

Then:

b = 6/15 = 2/5

b = 2/5 = 0.4
