Answer

$A$

Work Step by Step

The diagonals of a parallelogram bisect one another; therefore, we can set the two bisected segments of each diagonal equal to one another. Let's start with the diagonal in which the segments have the same variable: $3x - 2 = 5x - 6$ Subtract $5x$ from each side of the equation to move variables to the left side of the equation: $-2x - 2 = -6$ Add $2$ to each side of the equation to move constants to the right side of the equation: $-2x = -4$ Divide both sides by $-2$ to solve for $x$: $x = 2$ Now, we can set the other two segments on the other diagonal equal to one another: $6y - 4 = y + 1$ Add $4$ to each side of the equation to move constants to the right side of the equation: $6y = y + 5$ Subtract $y$ from each side of the equation to move variables to the left side of the equation: $5y = 5$ Divide both sides of the equation by $5$ to solve for $y$: $y = 1$
