3.14乘以X=16.56-X 越快越好!

3.14乘以X=16.56-X 越快越好! 2x乘以x乘以x=24,求x! 为什么3.14乘以X+X=4.14X X乘以X等于40 ---------------------X=? x乘以x+1乘以x+2乘以x+3=3024怎么解? (1+40%)乘以X乘以80%—X=15 lgx 乘以 log10 x=? 0乘以X=多少 (1+40%)乘以X乘以80%—X=15 (1+40%)乘以X乘以80%—X=15 x-(x乘以0.021)=100000 x-120=2乘以(x-200) [5x+9x乘以(66-x)]乘以(1-18%)=1.75x+7.2乘以(66-x) 解方程2乘以0.2x-3乘以0.3x+5乘以0.4x=0.3乘以5 （2x²）²乘以x³+（x²）³乘以x= 解方程x乘以(x+3)乘以(x+6)=1620 求x的解, x乘以5乘以x等于多少 25乘以(20-x)=30乘以15 0.3x-x乘以0.25=21.15-7x
