Find the values of x and y in parallelogram ABCD.
\n" ); document.write( "AB= 2y, BC= y + 3, CD= 5x-1, DA= 2x+4
\n" ); document.write( "--------
\n" ); document.write( "Equations:
\n" ); document.write( "AB = CD
\n" ); document.write( "AD = BC
\n" ); document.write( "---------------
\n" ); document.write( "2y = 5x-1
\n" ); document.write( "2x+4 = y+3
\n" ); document.write( "--------
\n" ); document.write( "Rearrange:
\n" ); document.write( "5x - 2y = 1
\n" ); document.write( "2x - y = -1
\n" ); document.write( "------------------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "5x - 2y = 1
\n" ); document.write( "4x - 2y = -2
\n" ); document.write( "--------------------
\n" ); document.write( "Subtract and solve for \"x\":
\n" ); document.write( "x = 3
\n" ); document.write( "----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "2y = 5x-1
\n" ); document.write( "2y = 15-1
\n" ); document.write( "y = 7
\n" ); document.write( "---------------------
\n" ); document.write( "AB= 2y = 14
\n" ); document.write( "BC= y + 3 = 10
\n" ); document.write( "CD= 5x-1 = 14
\n" ); document.write( "DA= 2x+4 = 10
