✔ 最佳答案
h-[2(h-1)+10]=5(h-34) h-[2h-2+10]=5h-170
h-2h+2-10]=5h-170
2-10+170=5h-h+2h
162=6h
h=27
2006-10-21 6:57 pm
h-(2h-2+10)=5h-170
h-2h+2-10=5h-170
-h-8=5h-170
-6h=-162
6h=162
h=27
h-2h+2-10=5h-170
-h-8=5h-170
-6h=-162
6h=162
h=27
2006-10-21 6:17 pm
h - [2(h - 1) + 10] = 5(h - 34)
h - (2h - 2 + 10) = 5h - 170
h - 2h + 2 - 10 = 5h - 170
-h - 8 = 5h - 170
-6h = -162
6h = 162
h=27
h - (2h - 2 + 10) = 5h - 170
h - 2h + 2 - 10 = 5h - 170
-h - 8 = 5h - 170
-6h = -162
6h = 162
h=27
