$x=7$

#### Work Step by Step

Opposite sides of a parallelogram are congruent. Therefore, $RS=VT$ (ignore the information for side $ST$). $RS=VT$ Substitute in known lengths... $4(x-2)=3x-1$ Distribute the four... $4x-8=3x-1$ Subtract $3x$ from both sides... $x-8=-1$ Add eight to both sides... $x=7$
