0.5x+1+(0.5x—1)1/3-1=x-150.5x+1+(0.5x—1)× 1/3 -1=x-15
0.5x+1+(0.5x—1)1/3-1=x-15
0.5x+1+(0.5x—1)× 1/3 -1=x-15
0.5x+1+(0.5x—1)1/3-1=x-150.5x+1+(0.5x—1)× 1/3 -1=x-15
1.5x+3+0.5x-1-3=3x-45
2x-1=3x-45
3x-2x=45-1
x=44
X=14
两边同时乘以3
移项
1.5x+3+0.5x-1-3=3x-45
2x-1=3x-45
3x-2x=45-1
x=44
方程两边同乘以3: 1.5x+3+0.5x-1-3=3x-45
2x-1=3x-45
x=-1+45=44
