x:(—25﹚=30:
x:(—25﹚=30:
x-60%x-25%x=25%x-30
(25/X)X(30/X)= 15/X怎么算
x-30%x=14x+25%x=20
解方程 65%x—30%x=35 x+5分之x=18 4分之3x+4分之1x=1
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
解方程:1.60%+25=40 2.X-10%X=18 3.x+30%X=52 4.(1-25%)X=36
x-(30%x+30%x+15)=25
(25%X-30)+110=15%X+X
2x=25+x 注意:
2.1x—1.6x=4
x—0.8x=0.
