详细解方程 x-（1/4x+7）-[2/5（x-1/4x-7）+2]=5/18x

x-（1/4x+7）-[2/5（x-1/4x-7）+2]=5/18x
x-1/4x-7-[2/5x-2/5×1/4x-2/5×7+2]=5/18x
3/4x-7-[2/5x-1/10x-14/5+2]=5/18x
3/4x-7-[3/10x-14/5+2]=5/18x
3/4x-7-[3/10x-4/5]=5/18x
3/4x-7-3/10x+4/5=5/18x
9/20x-7+4/5=5/18x
9/20x-5/18x=7-4/5
85/180x=31/5
17/38x=31/5
x=31/5÷17/38
x=31/5×38/17
x=1178/85答案是36哦算的乱七八糟的，真心不会算！我再算一遍吧！
