Question

Yang hồ cấp cứu!! Tôi vã lắm r ;v;

Answer 1

a) \(\dfrac{2x-1}{3}< \dfrac{x+6}{2}\)

\(\Leftrightarrow2\left(2x-1\right)< 3\left(x+6\right)\)

\(\Leftrightarrow4x-2< 3x+18\)

\(\Leftrightarrow x< 20\)

b) \(\dfrac{5\left(x-1\right)}{6}-1\ge\dfrac{2\left(x+1\right)}{3}\)

\(\Leftrightarrow5\left(x-1\right)-6\ge2.2\left(x+1\right)\)

\(\Leftrightarrow5x-5-6\ge4x+2\)

\(\Leftrightarrow x\ge13\)
