![x-(0.5x+5)-[0.5(0.5x+5)-10]-15=10](/uploads/image/z/580982-14-2.jpg?t=x-%280.5x%2B5%29-%5B0.5%280.5x%2B5%29-10%5D-15%3D10)
x-(0.5x+5)-[0.5(0.5x+5)-10]-15=10
x-(0.5x+5)-[0.5(0.5x+5)-10]-15=10
x-(0.5x+5)-[0.5(0.5x+5)-10]-15=10
x-(0.5x+5)-[0.5(0.5x+5)-10]-15=10先去中括号得 x-(0.5x+5)-0.5(0.5x+5)+10-15=10化简得 x-1.5(0.5x+5)=15去括号得 (1-1.5×0.5)x-1.5×5=15化简得 0.25x=22.5 x=90
(x+2)(x-1)+(x+3)(x+1)=x·x-1 求x (5x-4)(2x+5)(3x-6)(2x-4)=(2x-4)(2x+5)·0.5 求x
12x-2/21x=快点9点之前还有7x-x+2/3x-3(4x-0.5)-2x+(3x-1)-(x+5)
0.5X+120+0.3X=X
4X+0.5X=13.5X
x-30-0.2x=0.5x
x-0.3x-0.5x=20
9x+0.5x+x=
0.5x+(5x+20)*0.5=298 x
x/0.5
0.5x=4/5(6+x)x=?
0.5x/0.8=5 x=?
0.4x-1/0.5-5-x/2
0.4x-1/0.5-5-x/2
求x:|x|-|x-4|=0.5x-1
X+0.5X=3 X-0.8X=8
250x - 2(x+50)(x+0.5)求x
设f(x)=x^3-0.5x^2-2x+5 当x∈[-1,2],f(x)
