Hi Dear Schnitzel
-1 ≤ 3 – 2x < 11
It is our inequality

Part One;
-1 ≤ 3 – 2x
-1 -3 ≤ -2x
-4 ≤ -2x
{ multiply by -1 }
+4 ≥ +2x
4/2 ≥ x
2 ≥ x
x ≤ 2 Or ( - ∞ , +2]
Part Two;
3 – 2x < 11
-2x < 11-3
-2x < +8
{ again multiply by -1}
2x > -8
x > -8/2
x > -4 Or ( -4 , +∞)
................................................................................................

So ( - ∞ , +2] U ( -4 , +∞)

Good Luck ...

-1 <= 3 - 2x < 11 (Subtract 3 from each)
-4 <= -2x < 8 (Divide each by -2 and reverse signs)
2 >= x > -4
x is less than or equal to 2 and greater than -4

-1 ≤ 3 – 2x < 11?

this exp[ression is true for a range of values of x from 2 to (but not including ) -4

Start off adding 3 to EVERYTHING in order to colve for x.

Once that is completed, divide everything by -2 to isolate the variable in order to solve for x.

Graph accordingly.
