Answer :

To make [tex]\( c \)[/tex] the subject of the formula from the given equation [tex]\( 5a = \frac{b - 2c}{bc} \)[/tex], follow these steps:

1. Clear the fraction: To eliminate the fraction, multiply both sides of the equation by [tex]\( bc \)[/tex]:
[tex]\[ 5a \cdot bc = b - 2c \][/tex]
This simplifies to:
[tex]\[ 5abc = b - 2c \][/tex]

2. Rearrange the equation: Move all terms involving [tex]\( c \)[/tex] to one side of the equation:
[tex]\[ 5abc + 2c = b \][/tex]

3. Factor out [tex]\( c \)[/tex]: Extract [tex]\( c \)[/tex] as a common factor from the left side:
[tex]\[ c(5ab + 2) = b \][/tex]

4. Isolate [tex]\( c \)[/tex]: Finally, divide both sides by [tex]\( (5ab + 2) \)[/tex] to solve for [tex]\( c \)[/tex]:
[tex]\[ c = \frac{b}{5ab + 2} \][/tex]

Thus, the formula for [tex]\( c \)[/tex] in terms of [tex]\( a \)[/tex] and [tex]\( b \)[/tex] is:
[tex]\[ c = \frac{b}{5ab + 2} \][/tex]
