Question

Solve : - 12x > 30 when x is an natural number

Answer 1

Answer:

when x is natural number .

it means x is one of 1, 2 , 3 , 4 ......

e.g x is always positive number .

now,

-12x > 30

take both sides negative . from the rule of inequality sign change .

so, -(-12x) < -30

=> 12x < -30

divide by 12 both sides ,

=> x < -30/12

=> x < -2.5

there is no solution possible when x is natural number because less then -2.5 have no natural numbers .
