Solve the inequality 1 - 2x lt - frac 1 3 - WAEC Mathematics 2008 Question
Solve the inequality 1 - 2x < - \(\frac{1}{3}\)
A
x < \(\frac{2}{3}\)
B
x < -\(\frac{2}{3}\)
C
x > \(\frac{2}{3}\)
D
x > -\(\frac{2}{3}\)
correct option: c
1 - 2x < - \(\frac{1}{3}\); -2x < -\(\frac{1}{3}\) - 1
-2x < - \(\frac{1- 3}{3}\)
-2x < - \(\frac{4}{-6}\)
3x -2x < -4; -8x < -4
x > -\(\frac{4}{-6}\) = x > \(\frac{2}{3}\)
-2x < - \(\frac{1- 3}{3}\)
-2x < - \(\frac{4}{-6}\)
3x -2x < -4; -8x < -4
x > -\(\frac{4}{-6}\) = x > \(\frac{2}{3}\)
