3.8x-x=0.56
3.8x-x=5.3.8x-x=5.62.8x=5.6x=5.6除以2.8x=2
（X+X)+(X-X)+(X*X)+(X/X)=100（X+X)+(X-X)+(X*X)+(X/X)=1002X+0+X*X+1=1002X+X*X=99X(X+2)=99X=9因为(9+9)+(9-9)+(9×9)+(9÷9)=100，∴
8x=5x+24.98x=5x+24.98x-5x=24.93x=24.9x=8.3
13x-（4.5x+2.9)=0.5x+3.8×0.513x-（4.5x+2.9)=0.5x+3.8×0.513x-4.5x-2.9=0.5x+1.913x-4.5x-0.5x=1.9+2.98x=4.8x=4.8÷8x=0.68.5x-2
3x-3.8x+8x=3.6答3x-3.8x+8x=3.6(3-3.8+8)x=3.67.2x=3.6x=3.6÷7.2x=0.5
1.8x(3x-2.5)-3.8x=1.545.4X--4.5--3.8X=1.541.6X=1.54+4.51.6X=6.04X=6.04\1.6x=3.775这是一元二次方程吧
解方程：3.8x-x=0.563.8x-x=0.562.8x=0.56x=0.2有问题清追问3.8x-x=0.562.8x=0.56x=0.23.8x-x=0.562.8x=0.56x=0.23.8x-x=0.562.8x=0.56x=0.
解方程：3.8x-x=56
4X-3.8=25.9-4.5x4X-3.8=25.9-4.5x8.5x=29.7x=3.54x-3.8=25.9-4.5x8.5x=29.7x=29.7÷8.5x≈3.49
2X-3.8=25.9-4.5x2X-3.8=25.9-4.5x2X+4.5x=25.9+3.86.5x=29.7x=4.57结果是约等于吧
3.8x-x=0.56简易方程3.8x-x=0.562.8x=0.56x=5.6/28x=0.22.8x=0.56x=0.2
3.8x+5.2x=19.983.8x+5.2x=19.98(3.8+5.2)x=19.989x=19.98x=2.22
4.5x=2.5x+3.84.5x=2.5x+3.84.5x-2.5x=3.82x=3.8x=1.9x=1.9、
7x+2.5x=3.8解9.5x＝3.8x＝3.89.5x＝X=0.4（7+2.5）x=3.89.5x=3.89.5x除以9.5=3.8除以9.5x=4
3.8x-0.8x=4.5请放心使用,有问题的话请追问满意请及时采纳,谢谢,采纳后你将获得5财富值.你的采纳将是我继续努力帮助他人的最强动力!
2x(3.8-x)=0.5少了个条件?2次方程一个代数式?答案是3.55
7.2x-3.8x=12.67.2x-3.8x=12.6(7.2-3.8)x=12.63.4x=12.6x=64/17
5x+3.8-6x=5x+3.8-6x=-x=-3.8x=3.83.8-x化简吗3.8-x-x+3.8
3.8x-x=42怎么解?3.8x-x=42(3.8-1)x=422.8x=42x=42÷2.8x=152.8x=42X=153.8x-x=422.8x=42x=42/2.8x=153.8x-x=42(3.8-1)x=422.8x=42x=
