解方程:0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
解方程:0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3

解方程:0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
由0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
得,2x-0.75-x+0.16=0.12-0.1x+3
移项,化简得,1.1x=3.71
解得:x=371/11

0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
2x-0.75-x+0.16=0.12-0.1x+3
1.1x=0.12+3+0.75-0.16
x=3.71/1.1=3.37272

0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
2x-0.75-x+0.16=0.12-0.1x+3
1.1x=3.71
x=3.37272727...
