#### Answer

$x=7$

#### 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...
$x=7$
