EVALUATION

SOLVE FOR QUESTION : 1

$\displaystyle \sf{ a = \frac{1}{2}(b - c) }$

$\displaystyle \sf{ \implies \: 2 a =(b - c) }$

$\displaystyle \sf{ \implies \: 2 a + c =b}$

$\displaystyle \sf{ \implies \: b = 2 a + c }$

Which is the required expression where b as the subject

SOLVE FOR QUESTION : 2

$\displaystyle \sf{a = \frac{1}{2(b - c)} }$

$\displaystyle \sf{ \implies \: (b - c) = \frac{1}{2a} }$

$\displaystyle \sf{ \implies \: b= c + \frac{1}{2a} }$

$\displaystyle \sf{ \implies \: b= \frac{2ac + 1}{2a} }$

Which is the required expression where b as the subject
