0.5x+1.2+15.2=0.75x+9.1 怎么解
0.5x+1.2+15.2=0.75x+9.1 怎么解
0.5x+1.2+15.2=0.75x+9.1 怎么解
原题下来
1.2+15.2-9.1=0.75X-0.5X
16.4-9.1=0.25X
7.3=0.25X
X=29.2
0.25x=7.3
x=29.2
0.25x=7.3
x=29.2
0.5x+1.2+15.2=0.75x+9.1
-0.25x=-7.3
x=29.2
0.5x+1.2+15.2=0.75x+9.1 怎么解
17x+13=7x+38 1.9+0.75x-0.1=x 13x-3x=72=12x=30 9.4x-120=8.4x=17x-200 15.2x-0.8=7.4x+70.9x-0.5x+0.28=x+0.1
0.5x=0.75(1000-x)
0.5x-6=0.75x
0.75x+0.5x=2.25
1.2x-0.5x=6.
0.8X-0.5*1.2X=10
几道方程不会做.1:1.9+0.75x-0.1=x2:13x-3x+72=12x+303:9.4x-120=8.4x+17x-2004:15.2x-0.8=7.4x+75:0.9x-0.5x+0.28=x+0.1(注:要发完整的方程算式,不完整的不给分!)
(X+X)+(X-X)+(X*X)+(X/X)=100
2.6x-x-0.1x=0.75
0.5X+120+0.3X=X
4X+0.5X=13.5X
x-30-0.2x=0.5x
x-0.3x-0.5x=20
9x+0.5x+x=
4x一5/0.5—5x-0.8/0.2=1.2-x/0.1 x=
0.75x+x=17.5
x-25%x=0.75
