**Anonymous**, Thursday, September 6, 2012 at 2:11pm7 d - ( 1 / 2 ) ( 2 d - 4 ) = ( - 5 / 4 ) ( d + 4 )

7 d - ( 1 / 2 ) * 2 d - ( 1 / 2 ) * ( - 4 = ( - 5 / 4 ) * d + ( - 5 / 4 ) * 4

7 d - d + 2 = ( - 5 / 4 ) * d - 5

6 d + 2 = ( - 5 / 4 ) * d - 5

6 d + ( 5 / 4 ) d = - 5 - 2

( 24 / 4 ) d + ( 5 / 4 ) d = - 7

( 29 / 4 ) d = - 7 Multiply both sides by 4

29 d = - 28 Divide both sides by 29

d = - 28 / 29
