解方程 3(X-1)+16(2X-3)=-16 (2X+1)÷3-(X-1)÷6=2

问题描述:

解方程 3(X-1)+16(2X-3)=-16 (2X+1)÷3-(X-1)÷6=2

把最后的“=2”先不看
3X-3+32X-48=(32X+16)÷3-X÷6+1÷6
35X-51=65X÷6-32÷6+1÷6
210X-306=65X-32+1
210X-306=65X-31
145X=275
X=55/29

3(X-1)+16(2X-3)=-16
3x-3+32x-48=-16
35x-51=-16
35x=35
x=1
(2X+1)÷3-(X-1)÷6=2
2/3x+1/3-1/6x+1/6=2
1/2x+2/3=2
1/2x=4/3
x=8/3

3(X-1)+16(2X-3)=-16
3x-3+32x-48=-16
35x-51=-16
35x=35
x=1
(2X+1)÷3-(X-1)÷6=2
(2x+1)/3-(x-1)/6=2
2(2x+1)-(x-1)=12
4x+2-x+1=12
3x=9
x=3
