Answer

The point $(2,3)$ is the solution of the system.

Work Step by Step

Given: $2x+4y \leq 17$ and $6x+5y \leq 29$ Plug $x=2$ and $y=3$ in the inequality $4x-2y \geq 1$ I. $2(2)+4(3) \leq 17$ or, $4+12 \leq 17$ Thus $16 \leq 17$ II. $6(2)+5(3) \leq 29$ or, $12+15 \leq 29$ Thus, $27 \leq 29$ Hence, the point $(2,3)$ is the solution of the system.
