Question

Answer 1

\(\dfrac{2x-1}{3}-2\ge\dfrac{x}{5}\Rightarrow5.\left(2x-1\right)-30\ge3x\)

\(\Rightarrow5.2x-5-30\ge3x\)

\(\Rightarrow10x-5-30\ge3x\)

\(\Rightarrow10x-3x\ge5+30=>7x\ge35\)

\(=>x\ge5\)

 

Answer 2

=>5(2x-1)-30>=3x

=>10x-5-30>=3x

=>7x>=35

hay x>=5

Answer 3

=>5(2x-1)-30>=3x

=>10x-5-30>=3x

=>7x>=35

hay x>=5
