8(x-0.5)=7.
8x-0.5x=0.5x-21怎么算
5*(x-2)=4*(x+3) 2x+(50-x)*4=140 3x-(8-x)=20*4 200x=(x-0.5)*2
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
X-0.5X-12-0.5(X-0.5X-12)-8=18怎么解
30%x+0.5x=1/4x+8/5x=多少
11x+0.5=15x-0.7 5x+12=8x+3
y=2x^2-4x-8 y=0.5x^2+2x-1
8x-0.5x=37.5 5x+3x=19.2解方程
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
( 3.6-1)x=3.25 12.5x-0.9x=52.2 x-0.72x=0.336 8x-0.5x=37.5 0.
2(0.9-x)+4=4.3.(x+1.8)/8=6.6.12x+12=16x.12x-35=5x.X/0.5-10+2
