Find all values of x satisfying the inequality ... - JAMB Mathematics 1992 Question
Find all values of x satisfying the inequality -11 \(\leq\) 4 - 3x \(\leq\) 28
A
-5 \(\leq\) x v 8
B
5 \(\leq\) x \(\leq\) 8
C
-8 \(\leq\) x \(\leq\) 5
D
-5 < x \(\leq\) 8
correct option: c
To solve -11 (\leq) 4 - 3x (\leq) 28
-11 (\leq) 4 - 3x also 4 -3x (\leq) 28
15 (\leq) -3x (\leq) 24 = 15 (\geq) 3x - 3x (\geq) -24
-5 (\geq) x, x (\geq) -8
i.e. x (\leq) 5
∴ -8 (\leq) x (\leq) 5
