Write and solve an inequality for the possible values of x

The inequality to find the possible values of [tex]x[/tex] is required.
The solution is [tex]x>-1.5[/tex]
[tex]AB=BC=DC=2x[/tex]
[tex]AC=AB+BC=2x+2x\\\Rightarrow AC=4x[/tex]
In a triangle the sum of any two sides is greater than the third side
So,
[tex]AC+DC>AD[/tex]
[tex]\Rightarrow 4x+2x>4x-3[/tex]
[tex]\Rightarrow 6x>4x-3[/tex]
[tex]\Rightarrow 2x>-3[/tex]
[tex]\Rightarrow x>-\dfrac{3}{2}[/tex]
[tex]\Rightarrow x>-1.5[/tex]
