(25-30)*1.5%x+x=1323 x=?
(25-30)*1.5%x+x=1323 x=?
(25-30)*1.5%x+x=1323 x=?
(25-30)*1.5%x+x=1323
-7.5%x+x=1323
92.5%x=1323
x=1430.27
(25-30)*1.5%x+x=1323 x=?
30/x=30/(x-1.5)-x
(25%X-30)+110=15%X+X
(30-x)+x+(25-x)=50求过程,
x-60%x-25%x=25%x-30
x-30%x=14x+25%x=20
(25/X)X(30/X)= 15/X怎么算
60%x+25=40 x+30%x=52 19-120%x=7 4分之3x-5%x=17.5 x-10%x=18 (1-25%)x=36 2x+30%x=9.2
0.3+0.3x=0.39 x= 2x-1.5x=7.6x x= 0.36x÷0.3=1.2 x=6(x+1.2)=18.6 x= 7x+2x = 8.1 x= (x-5)÷3=1.7 x=5(x+1.1)=15.5 x= 9x+25=70 x= 7x-4x=2.1 x=
(x+x)+(x-x)+(x/x)=11.2
x+ x+(x*50%)=1.5X?
(x+30)*(x-18)=x*x
x除55%=100 60%x=30 x+50%x=4.5 (1-25%)x=72 4x+40%x=176 解方程
解方程:x/4=30% 36/x=3/4 10/x=2.5/0.8 x/4=1.2/5 X/1.2=1.5/0.6 x/0.4=1.5/6 x/7=0.6/3.5 x/10=0.1/25-3x=8x+1 2(x-2)+2=x+1 3-x=2-5(x-1) 3x=5(32-x) 7(4-x)=9(x-4) 7x-8=2x+27 5x-18=3-2x (7x-4)+3(x-2)=2x+6 2(3x-4)+(4-x)=4x我是六年级的学生,我希望
12—120%X=6 5分之3X—5%X=5.5 (1+25%)X=7.5 X—30%X=91 4%X+6%X=29.4 X+25%X=8.75
(35-20)*1.5%*x+x=1323
[35-20]*1.5x+x=1323
(X-17)+(X-21)+(X-25)+.+(X-57)=33,求X=?
