题目：

Ⅹ-0.25=1/4 2/3Ⅹ+1/2Ⅹ=42 0.5/7=Ⅹ/35
解： = = =
= = =

Answer 1

您好：

Ⅹ-0.25=1/4
x=1/4+1/4
x=1/2

2/3Ⅹ+1/2Ⅹ=42
7/6x=42
x=42÷7/6
x=36

0.5/7=Ⅹ/35
x=35x1/14
x=5/2

Answer 2

Ⅹ-0.25=1/4 x=0.25+1/4=1/4+1/4=1/2
2/3Ⅹ+1/2Ⅹ=4 通分 4/6 x+3/6 x=42 7/6 x=42 x=42*6/7=36
0.5/7=Ⅹ/35 通分 1/14=x/35 两边分别乘以35 x=1/14 *35 x=5/2
