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
