1.7x-120%x=6.51.7x-120%x=6.51.7x-120%x=6.5初一的吧1.7x-120%x=6.51.7x-1.2x=6.50.5x=6.5x=6.5除以0.5x=1.3
1.7x-120%x=6.5
1.7x-120%x=6.5
1.7x-120%x=6.5
初一的吧
1.7x-120%x=6.5
1.7x-1.2x =6.5
0.5x =6.5
x =6.5除以0.5
x =1.3
1.7x-120%x=6.5 x=?
1.7x-120%x=6.5
1.7x-120%x=6.5
1.7x-120%x=6.5 怎么解
5X(X--6.5)=1.7
11x+120%x=6.5
12/11x+120%x=6.5
（X+X)+(X-X)+(X*X)+(X/X)=100
x(120+x)*80％=x-76
x(x+1)(x-1)=120
x-x/4-120=x/2
0.5X+120+0.3X=X
x/（120-x）=x/60
x/(120-x)=(60-x)/60
25%X+三分之一X+120=X
536-120%x-x=x-80
解方程：（1）20%x+45%x=1.3 （2） 2x+9分子2*5=2 （3）1.7x-120%x=6.5 (4） x-35%x=39
6.5x-4.5x=93.6-6.5x-3.5x
