Question 1159512: What is the value of d in the equation below? Round you answer to the nearest hundredth.
1/5 (9 +2) +3 = 1/4 (4-d) + 1
1/5 ( 11 ) +3 = 4/4 -d/4 + 1
11/5 + 3 = 1 - d/4 + 1
11/5 + 3×5/5 = 2 - d/4
11/5 + 15/5 = 2 - d/4
26/5 = 2 - d/4
d/4 = 2 - 26/5
d/4 = 2×5/5 -26/5
d/4 = 10/5-26/5
d/4 = -16/5
d = 4×-16/5
d = -64/5
d = -12.8
d nearest hundred solution of d = -100

You can put this solution on YOUR website!
in case you have this:
%281%2F5%29%289+%2B2%29+%2B3+=+%281%2F4%29+%284-d%29+%2B+1
%281%2F5%29%2811%29+%2B3+=+%284-d%29%2F4+%2B+1
11%2F5+%2B3+-1=+%284-d%29%2F4+
11%2F5+%2B2=+%284-d%29%2F4+.....both sides multiply by 4
4%2811%2F5%29+%2B2%2A4=+4-d
44%2F5+%2B8=+4-d
d=4-44%2F5+-8
d=-64%2F5
d=-12.80

in case you have this:
1%2F5%289+%2B2%29+%2B3+=+1%2F4%284-d%29+%2B+1
1%2F55+%2B3+=+1%2F%2816-4d%29+%2B+1
1%2F55+%2B3-1+=+1%2F%2816-4d%29+
1%2F55+%2B2+=+1%2F%2816-4d%29+
1%2F55+%2B110%2F55+=+1%2F%2816-4d%29+
111%2F55=+1%2F%2816-4d%29+....cross multiply

%2816-4d%29111=+1%2A+55
16-4d=+55%2F111
16-55%2F111=4d
1721%2F111=4d
1721%2F%284%2A111%29=d
d=1721%2F444
d=3.88
