14. Solve the following inequality:

$space space minus 15 less than fraction numerator 3 left parenthesis straight x minus 2 right parenthesis over denominator 5 end fraction less or equal than 0$

space space minus 15 less than fraction numerator 3 left parenthesis straight x minus 2 right parenthesis over denominator 5 end fraction less or equal than 0

Now,

negative 15 less than fraction numerator 3 space left parenthesis straight x minus 2 right parenthesis over denominator 5 end fraction rightwards double arrow space minus 75 less than 3 space left parenthesis straight x minus 2 right parenthesis space rightwards double arrow negative 75 space less than space 3 straight x minus 6 rightwards double arrow space minus 3 straight x less than negative 6 plus 75

rightwards double arrow

-3x < 69

rightwards double arrow space space space space space space space space fraction numerator negative 3 straight x over denominator negative 3 end fraction greater than fraction numerator 69 over denominator negative 3 end fraction

(∵ -3 < 0)

rightwards double arrow

x > -23 ...(i)

...(ii)

From (i) and (ii), we have -23 < x

less or equal than

2 which is the required solution of the given inequality.

Hence, the solution set is (-23, 2].
