What will be the solution of (1 to 3) system of inequality : $5x + 1> -24, 5x-1< 24$
Answer & explanation
Correct answer: option 4
The correct answer is option (4) : $ (-5, 5)$
|
$5x+1> -24$ $5x> -25$ $x> -5$ $-5< x$ ......(i) |
$5x-1< 24$ $5x< 25$ $x< 5$ ......(ii) |
From (i) and (ii)
$-5< x < 5$
Hence Solution set is {x : x ∈ R, -5 < x< 5}
i.e $ (-5, 5)$
