Answer:
[tex]B = \frac{g}{m-2g}[/tex]
Step-by-step explanation:
Given
[tex]g = mB - 2qB[/tex]
Required
Solve for B
[tex]g = mB - 2qB[/tex]
Factorize the expression
[tex]g = B(m - 2q)[/tex]
Divide both sides by m - 2g
[tex]\frac{g}{m-2g} = \frac{B(m - 2q)}{m-2g}[/tex]
[tex]\frac{g}{m-2g} = B[/tex]
Reorder
[tex]B = \frac{g}{m-2g}[/tex]
