Answer

No solution. The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow 6(2x-1)\geq 3(4x+1)$ Use distributive property. $\Rightarrow 12x-6\geq 12x+3$ Add $6$ to each side. $\Rightarrow 12x-6+6\geq 12x+3+6$ Simplify. $\Rightarrow 12x\geq 12x+9$ Subtract $12x$ from each side. $\Rightarrow 12x-12x\geq 12x+9-12x$ Simplify. $\Rightarrow 0\geq 9$ The inequality is false. Hence, there is no solution.
