Question

x+0.25x=90解方程？

Answer 1

x+0.25x=90
这是一个一元一次方程，解决方法是把含有未知数的项移到一边，常数项移到另一边。然后合并同类项。
1.25x=90 把未知数的系数变成一，两边同时除以1.25
x=90/1.25=72

Answer 2

1.25。方程1.25*4-0.25x=0.95*4-0.25x=0.95*4-4-x=3.6x=20-3.6x=20-3.6x=20-3.6x=16.4 5-0.25x=0.90.25x=0.90.25x=5-0.25x=0.90.25x=5-0.25x=0.90.25x=0.90.25x=5-0.90.25x=5-0.90.25x=5-0.90.90.25x=5-0.9x=0.9x=0.90.90.9x=0.90.90.90.90.90.采用溶液：5-0.25x=0.9.0.25x=0.25x=5.0.0.0.9 x=16.4 1.25*4-0.25 x=0.95-0.25 x=0.90.25 x=5-0.90.25 x=4.1 x=16.4 1.25×4-0.25 x=0.95-0.25 x=0.90.25 x=5-0.90.25 x=4.1 x=4.1△0.25 x=16.4

Answer 3

1.25。方程1.25*4-0.25x=0.95*4-0.25x=0.95*4-4-x=3.6x=20-3.6x=20-3.6x=20-3.6x=16.4 5-0.25x=0.90.25x=0.90.25x=5-0.25x=0.90.25x=5-0.25x=0.90.25x=0.90.25x=5-0.90.25x=5-0.90.25x=5-0.90.90.25x=5-0.9x=0.9x=0.90.90.9x=0.90.90.90.90.90.采用溶液：5-0.25x=0.9.0.25x=0.25x=5.0.0.0.9 x=16.4 1.25*4-0.25 x=0.95-0.25 x=0.90.25 x=5-0.90.25 x=4.1 x=16.4 1.25×4-0.25 x=0.95-0.25 x=0.90.25 x=5-0.90.25 x=4.1 x=4.1△0.25 x=16.4

Answer 4

方程1.25*4-0.25x=0.9的解为16.4。具体方程如下：5-0.25*0.25x=0.95*4-x=3.6x=20-3.6x=16.45-0.25mx=0-0.9x=4.1/0.24x=16.4。我们希望采用以下解决方案：5-0.25x=0.9 0.25x=5-0-9 x=16.4 1.25*4-0.25 x=0.95-0.25mx=0.90.25x=5-0.90.25x=4.1x=16.1 1 1.25

Answer 5

你好，这道题是一元一次方程。合并同类项得1.25x=90，等式两边同时除以1.25得x=90/1.25=72，所以方程的解是x=72。
