(82+x)/22=[(706+x)]*0.5
(x-22)+(x-24)+(x-27)+(x-20)=x
(X+X)+(X-X)+(X*X)+(X/X)=100
4X+0.5X=13.5X
x-4x=102 x-0.8x=22
解方程:x+3x=148 15x-8x=5.6 6x-x=96 2除以x=0.5 3x+3=84 6x=14x=82-5
x+0.5x=30
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
x+x=x+15
0.5x+31-x=22(解方程)
X/6-(5X-22)/9=0.5
6X-(360X-0.5X)=2×(360X-0.5X)
