Question

解方程：2-10x/3-3/2=2-6x/5

Answer 1

2一(10/3)x一3/2=2一(6/5)x
解:去分母(方程两边同时乘以30)得:
60一100x一45=60一36ⅹ
移项得:
一100x+36x=60一60一45
合并同类项得:
一64ⅹ=一45
系数化为1得:
x=45/64。

Answer 2

解方程：2-10x/3-3/2=2-6x/5
方程二边同时乘以30得出
60-100x-45=60-36x
-100x+36x=60-60+45
-64x=45
x=-45/64

Answer 3

2-10x/3-3/2=2-6x/5
6/5x-10/3x=2-2+3/2
36x-100x=45
-64x=45
x=-45/64

Answer 4

2-10x/3-3/2=2-6x/5
-10x/3+6x/5=3/2
-50x/15+18x/15=3/2
-32x/15=3/2
x=3/2 *(-15/32)=-45/64
