Make m the subject of the formula m/v - t/b = m-t/r

RoseWind [281]

Answer:

$m = - \frac{ \frac{t}{b} + \frac{t}{r} }{1 - \frac{1}{v} }$

Step-by-step explanation:

$\frac{m}{v} - \frac{t}{b} = m - \frac{t}{r} \\ \frac{m}{v} - \frac{t}{b} + \frac{t}{r} = m \\ - \frac{t}{b} + \frac{t}{r} = m - \frac{m}{v} \\ - \frac{t}{b} + \frac{t}{r} = m(1 - \frac{1}{v} ) \\ - \frac{t}{b} + \frac{t}{r} = \frac{m( 1 - \frac{1}{v}) }{(1 - \frac{1}{v}) } \\ - \frac{ \frac{t}{b} + \frac{t}{r} }{1 - ( \frac{1}{v} ) } = m$

Answer:

Read below

Step-by-step explanation:

a) $\frac{-7}{9} = -\frac{7}{9} = \frac{7}{-9}$

b) $\frac{4}{3} =\frac{-4}{-3}$ (The reason both numerator and denominator can both be negative is because the negative cancel each other out and still simplify to $\frac{4}{3}$ )
