0.2x+0.45/0.25-0.015+0.01x/0.015=0.5x-2.5
如何解0.2x+0.45/0.25-0.015+0.01x/0.1-015=0.5x-2.5
求1/2x^2-1/4x+0.2x^3+0.25x-0.5x^2-1/5x^3+0.5x-1 其中x=12/13
(X+X)+(X-X)+(X*X)+(X/X)=100
3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4x[这个x是乘】2.5=3.6 3x+5x=
16+0.2x=0.25x十9求x!
x-2/0.2-x+1/0.5=3 x=?
15=2.5X一0.5X X=?
4-x=2(-0.5x²+2.5x-2)
2x-0.8×2.6=3.08-2x 2.4×0.2x=0.5x-2.4 5(0.2x-2.5)=2.1x
x-0.2x=80 求x
4X+0.5X=13.5X
解方程X-0.5X=15 X-0.8X=10 2.5X+2X=9
