1.7x-120%x=6.5
1.7x-120%x=6.5
1.7x-120%x=6.5
1.7x-120%x=6.5
1.7x-1.2x=6.5
0.5x=6.5
x=13
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
