What will be the solution of (1 to 3) system of inequality : $4-5x>-11, 4x+11≤-13$
Answer & explanation
Correct answer: option 3
The correct answer is option (3) : $(-∞, -6]$
|
$4-5x>-11$ $-5x>-15$ $x< 3$ ........(i) |
$4x+11≤-13$ $4x≤-13-11$ $4x≤-24$ $x≤-6$ .........(ii) |
From (i) and (ii)
$x≤-6$
Hence, Solution set is {x : x ∈ R, x ≤ -6 }
i.e $(-∞, -6]$
