Solution

Dear Student,

$\frac{2 m}{3} = 40 P u t m = 15 i n L H S : \frac{2 \times 15}{3} = 2 \times 5 = 10 L H S \neq R H S H e n c e, m = 15 i s n o t t h e s o l u t i o n . P u t m = 30 i n L H S : \frac{2 \times 30}{3} = 2 \times 10 = 20 L H S \neq R H S H e n c e, m = 30 i s n o t t h e s o l u t i o n . P u t m = 45 i n L H S : \frac{2 \times 45}{3} = 2 \times 15 = 30 L H S \neq R H S H e n c e, m = 45 i s n o t t h e s o l u t i o n . P u t m = 60 i n L H S : \frac{2 \times 60}{3} = 2 \times 20 = 40 L H S = R H S H e n c e, m = 60 i s t h e s o l u t i o n . A n s w e r : m = 60$
