6(x+1.2)=18.6
x+1.2=18.6÷6
x+1.2=3.1
x=3.1-1.2
x=1.9
7(x+1.2)=8.4
x+1.2=8.4÷7
x+1.2=1.2
x=1.2-1.2
x=0
6(x+1.2)=18.6
6x+6*1.2=18.6
6x=18.6-7.2
6x=11.4
x=1.9
7(x+1.2)=8.4
7x+8.4=8.4
7x=0

x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
2x+3x+4x+5x+x+6x+7x=100
(x+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
(x+8)(x+6)(x+7)+(x+5)(x+6)(x+7)=(x+5)(x+8)(x+7)+(x+5)(x+8)(x+6)
