x:4.5=5.8:2.9,x:4.5=5.8:2.9,x:4.5=5.8:2.9,x:4.5=5.8:2.92.9x=4.5×5.82.9x=26.1x=9右边就是2:1,x当然就是9喽x=4.5*
x:4.5=5.8:2.9,
x:4.5=5.8:2.9,
x:4.5=5.8:2.9,
x:4.5=5.8:2.9
2.9x=4.5×5.8
2.9x=26.1
x=9
右边就是2:1,x当然就是9喽
x=4.5*5.8/2.9=9
完毕@
x:4.5=5.8:2.9,
13x-(4.5x+2.9)=0.5x+3.8×0.5
5.8x-4.5x=7.8
5.8X-4.5X=7.8 x=5.8X-4.5X=7.8 x=( )解方程
4.5+x=6.2 x-3.8=6.6 4x=1 5x+7=42 2(x-5)=5.8 3.6x-x=5.8
9x+7x-x=4.5
5.8x-4.5=7.8
解比例 0.49/9.8=16/x 3/4:11/12=x:1/20 x:4.5=5.8:2.解比例0.49/9.8=16/x3/4:11/12=x:1/20x:4.5=5.8:2.9
X+0.45X=2.9
x+0.45x=2.9
x+ 5.8x=12
解方程 6.2x+4.5=5.8x+4.7
有7x+2x=140 9.3x+5.7x=4.5 6x+3x=180 7x-5x=16 7.8x-2.4x=1.08 5.8x+9.2x=72 25x+35x=460 跪谢
4.5x+x=12
x+4.5x=0.
