You could separate into two fractions leaving:
(z+5)/4 + 5/2
= z/4 + 5/4 + 5/2
= z/4 + 15/4
= (z+15)/4
(z+5)/4 + 5/2
= z/4 + 5/4 + 5/2
= z/4 + 15/4
= (z+15)/4

[(z + 5)/2 + 5]/2
= [(z + 5)/2 + 10/2]/2
= [(z + 5 + 10)/2]/2
= [(z + 15)/2]/2
= [(z + 15)/2](1/2)
= (z + 15)/4
= [(z + 5)/2 + 10/2]/2
= [(z + 5 + 10)/2]/2
= [(z + 15)/2]/2
= [(z + 15)/2](1/2)
= (z + 15)/4

((z+5)/2 +5)/2
=(z+5+10)/4
=(z+15)/4
=(z+5+10)/4
=(z+15)/4

(z+5)/7/2
(z+15)/3.5
(z+15)/3.5

(1/4)(z+5+10)
z = -15
z = -15

(z+15)/4
2009-12-29 2:24 pm
[ ( z + 5 ) / 2 + 5 ] / 2
( z + 5 ) / 4 + 5 / 2
(1/4) ( z + 5 + 10 )
(1/4) ( z + 15 )
( z + 5 ) / 4 + 5 / 2
(1/4) ( z + 5 + 10 )
(1/4) ( z + 15 )
