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,∞)
Answer:

Step-by-step explanation:
we have

Convert to standard form

where
A is a positive integer
B and C are integers
Multiply by 4 both sides to remove the fraction

subtract 4y both sides

Adds 12 both sides
