3.85+1.5x=6.1怎么解方程?

3.85+1.5x=6.1 1.5x=6.1-3.85 1.5x=2.25 x=2.25÷1.5 x=1.5

3.85+1.5x=6.1 1.5x=6.1-3.85 1.5x=2.25 x=2.25/1.5 x=1.5 手打不易,望采纳!

解方程 3.85+1.5x=6.1 1.5x=2.25 x=1.5 所以原方程的解为x=1.5

3.85+1.5x=6.1 1.5x=6.1-3.85 1.5x=2.25 x=2.25÷1.5 x=1.5

①3.85+1.5x=6.1,3.85+1.5x-3.85=6.1-3.85, 1.5x=2.25, 1.5x÷1.5=2.25÷1.5, x=1.5;②x÷1.44=0.4,x÷1.44×1.44=0.4×1.44, x=0.576;③2(x+5)=13.6,2(x+5)÷2=13.6÷2, x+5=6.8, x+5-5=6.8-5, x=1.8;④x-0.36x=16, 0.64x=16,0.64x÷0.6...

①3.85+1.5x=6.1, 3.85+1.5x-3.85=6.1-3.85, 1.5x=2.25, 1.5x÷1.5=2.25÷1.5, x=1.5;②x÷1.44=0.4,x÷1.44×1.44=0.4×1.44, x=0.576;③2(x+5)=13.6,2(x+5)÷2=13.6÷2, x+5=6.8, x+5-5=6.8-5, x=1.8;④x-0.36x=16, 0.64x=16,0.64x÷0.6...

3.85+1.5✘=6.1 解:1.5x=6.1-3.85 1.5x=2.25 x=2.25÷1.5 x=1.5

①3.85+1.5x=6.1, 3.85+1.5x-3.85=6.1-3.85, 1.5x=2.25, 1.5x÷1.5=2.25÷1.5, x=1.5;②3.6x-0.9x=5.4,(3.6-0.9)x=5.4, 2.7x=5.4, 2.7x÷2.7=5.4÷2.7, x=2;③6×3-2x=5, 18-2x=5, 18-2x+2x=5+2x, 5+2x=18, 5+2x-5=18-5, 2x=13, 2x÷2=...

你漏了符号,3.85一1.5x=5.1,一1.5X=1.25,x=一5/6。或3.85十1.5x=5.1,1.5x=1.25,x=5/6

3.85-1.5x=6.1 1.5x=3.85-6.1 1.5x=-2.25 x=-1.5
