解方程：（x-8000 ）·（1+10%）= (1+35%)x-11800
（x-8000 ）·（1+10%）= (1+35%)x-11800
最后结果是12000

解
(x-8000)(1+10%)=(1+35%)x-11800
(x-8000)×1.1=1.35x-11800
1.1x-8800=1.35x-11800
1.1x-1.35x=8800-11800
-0.25x=-3000
x=12000
(x-8000)(1+10%)=(1+35%)x-11800
(x-8000)×1.1=1.35x-11800
1.1x-8800=1.35x-11800
1.1x-1.35x=8800-11800
-0.25x=-3000
x=12000
