Solve -4x is less then equal to -16.

Question

I got x is less then equal to 4.

Is this correct I'm kind of confused with this question.

Answer 1

what's wrong with symbols?
-4x <= -16
divide by -4 to get
x >= 4

Another way to avoid multiplying by negative values and worrying about the direction of the inequality, is to make sure all values are positive.

-4x <= -16 -- add 4x to both sides
0 <= 4x-16 -- add 16 to both sides
16 <= 4x
4 <= x
which is the same answer. Multiplying/dividing by a negative value is just a shortcut for moving the item to the opposite side of the inequality.

Answer 2

-4x <= -16

x => 4
