人气:344 ℃ 时间:2020-02-03 20:01:53
解答
4-6x/0.01-6.5=0.02-2x/0.02-7.5
4-600x-6.5=0.02-100x-7.5
4-6.5+7.5-0.02=500x
500x=4.98
X=0.00996
推荐
4−6x0.01−6.5=0.02−2x0.02−7.5.
方程0.01分之4-6x-6.5=0.02分之0.02-2x-7.
0.01分之4-6x减去6.5=0.02分之0.02-2x减去7.5
(4-6x)/0.01-6.5+(0.02-2x)/0.02-7.5(注意解方程按步骤先通分再去分母再移向的做法)
解方程4-6x/0.01+1=0.02-2x/0.02和2|2x-1|+1=5
