Question

What is the solution of the inequality -4.0x-1.2>0.8

Answer 1

The answer to that should be x < -5

Answer 2

solution of the inequality will be x < (-5)

Explanation:

-0.4x - 1.2 > 0.8 is the given inequality.

Now we have to determine the solution of it.

first we divide this inequality by 4

`(1)/(0.4)(-0.4x-1.2)` >
`(0.8)/(0.4)`

-x - 3 > 2

- x - 3 + 3 > 2 + 3 [By adding 3 on both the sides of the inequality]

-x > 5

Now we reverse the inequality to change the sign of x

-(-x) < -(5)

x < (-5)

Therefore, solution of the inequality will be x < (-5)
