x+x+(188-x)+(180-x)=368x的解x+x+(188-x)+(180-x)=368x的解x+x+(188-x)+(180-x)=368x的解x+x+(188-x)+(180-x)=36
x+x+(188-x)+(180-x)=368 x的解
x+x+(188-x)+(180-x)=368 x的解
x+x+(188-x)+(180-x)=368 x的解
x+x+(188-x)+(180-x)=368
2x+188-x+180-x=368
368=368
∴原方程的解是全体实数
x+x+(188-x)+(180-x)=368
2x+368-2x=368
368=368
此式恒成立
因此x为一切实数。
(也即x∈R)

x+x+(188-x)+(180-x)=368 x的解
2x +188+180 = 368x
366x = 368
x = 368 / 366 = 184 / 183
x+x+(188-x)+(180-x)=368 x
x+x+188-x+180-x=368 x
368=368X
X=1
