Answer:
x > -4
Interval notation is (-4,∞)
Step-by-step explanation:
We need to get x alone
To get x alone , we need to remove -1/2 from left hand side
To remove denominator 2 we multiply both sides by 2
-1x> 4
To remove -1 , divide both side by -1
When we divide or multiply by negative then reverse the inequality symbol
x > -4
Interval notation is (-4,∞)
