Question

这解方程怎么做？

(1)25/x-10/60=30/(1+80%)

Answer 1

25/x-10/60=30/(1+80%)
30/(1+80%)=30/1.8=50/3
50/3+10/60=101/6
25/x=101/6
x=150/101

Answer 2

25/x-10/60=30/(1+80%)
25/x-1/6=30/1.8
25/x-1/6=50/3
两边乘以6x，得
150-x=100x
移项合并同类项，得
101x=150
x=150/101

Answer 3

解依题意得
25/x-10/60=30/(1+80%)
30/(1+80%)=30/1.8=50/3
50/3+10/60=101/6
25/x=101/6
x=150/101

Answer 4

25/x-10/60=30/(1+80%)
25/x-1/6=100/6
25/x=101/6
x=150/101

Answer 5

25/Ⅹ-10/60=30/（1+80%）
解：先进简单计算
25/Ⅹ-1/6=50/3
去分母，每项乘以6Ⅹ
25×6-Ⅹ=100Ⅹ
移项
100Ⅹ+Ⅹ=150
合并同类项
101Ⅹ=150
两边同时除以Ⅹ的系数101
X=150/101≈1.49
