Question

W= 2a + 3b for b ??????????

Answer 1

Hi :)

Let's make $b$ the subject of the formula. This is exactly the same as solving the equation for $b$.

This is how we'll go about finding $b$:

W=2a+3b

Let's get 2a out of the way by subtracting both sides by $2a$:

W-2a=3b

Now just divide the whole equation by $3$

$\frac{W-2a}{3}=b}$

We can turn this around. It won't change anything, as long as these two sides are equal

$b=\frac{W-2a}{3}$

Answer 2

Answer:

$b = \frac{w - 2a}{3}$

Step-by-step explanation:

Hello!

We are basically asked to solve for "b" or make "b" the subject.

Solve for b

• w= 2a + 3b
• w - 2a = 3b
• $\frac{w - 2a}{3} = b$

The solution is $b = \frac{w - 2a}{3}$.
