−2x≤3x−8<1

⇒−2x≤3x−8 and 3x−8<1

⇒8≤3x+2x ⇒3x<1+8

⇒8≤5x ⇒3x<9

≤x ⇒x<3

∴ The solution set is {x:1.6≤x≤3,xϵR}

hope it helps ☺️

The set of the solution is

2 \leqslant x &lt; 7

as represented on number line So,

 -13 &lt; 1 - 2x \leqslant  -3

multiply with -1 in inequality we get,

13 &gt;  - 1 + 2x \geqslant 3

Add with 1 in inequality we get,

14 &gt; 2x \geqslant 4

Divide by 2 we get

7 &gt; x \geqslant 2

as we see here this set of solution is our given set so,

option A is our solution.
