rearrange the equation a=1/2b (cd+e) for the quantity of interest B

Answer 1

To rearrange the equation \( a = \frac{1}{2} b (cd + e) \) for the quantity \( b \), follow these steps:

1. Multiply both sides by 2 to eliminate the fraction: \[ 2a = b (cd + e) \]

2. Now, divide both sides by \( (cd + e) \) to isolate \( b \): \[ b = \frac{2a}{cd + e} \]

So, the rearranged equation for \( b \) is: \[ b = \frac{2a}{cd + e} \]
