600=1.2x-0.8x600=0.4xx=600/0.4x=1500
你在读小学吧...0.2x=9.6解得:x=48
6x=24x=41.58*4=6.3210x=8x=0.870*0.8-29.5=26.5再问:确定答案吗?直接采纳喽
(1)0.8x+0.4x=1.2, 1.2x=
5x-18.5=03.5x=18.8x=3.766x7-6x=9.642-6x=9.66x=32.4x=5.43.4x-48=26.83.4x=74.8x=2242x+25x=13467x=134x=
x/4=30%x=4*30%=120%36/x=3/43x=36*4x=36*4/3=4810/x=2.5/0.82.5x=10*0.8x=10*0.8/2.5=3.2x/4=1.2/55x=4*1.
再答:再问:第一道题是什么,能打字打出来吗?再答:
(X+X)+(X-X)+(X*X)+(X/X)=1002X+0+X*X+1=1002X+X*X=99X(X+2)=99X=9再问:请问X(X+2)=99解为什么就等于9了呢没看懂再答:换成算术法你就明
0.8X-0.6X=100.2X=10X=50验算:0.8*50-0.5*1.2*50=40-30=10左右相等则X=50是次方程的解.
