Hi!
We need to isolate x on one side.
Whatever we do to the equation, we do it to both sides.
-6 ≥ 10 - 4x
Subtract 10 from both sides.
-6 - 10 ≥ 10 - 10 - 4x
-16 ≥ -4x
Divide by -4 on both sides. (because we divide by a negative number, we flip the inequality sign)
-16/-4 ≥ -4x/-4
4 ≤ x
Now none of the options are 4 ≤ x. So let's flip the equation to find the answer.
The answer is x ≥ 4
Hope this helps! :)
