4.8x 10.7x 4.96

解由题知15.5=4.96 两边除以15.5、 x=0.32解得

4.8X+10.7X=4.96 15.5X=4.96 X=4.96/15.5

4.8x+10.7x=4.96 15.5x=4.96 x=4.96/15.5

4.8x+10.7x=4.96;15.5x=4.96;x=0.32;x-0.8x=3.60.2x=3.6;x=18;请采纳如果你认可我的回答,敬请及时采纳,~如果你认可我的回答,请及时点击【采纳为满意回答】按钮~~手机提问的朋友在客户端右上角评价点【满意】即可.~你的采纳是我前进的动力~~O(∩_∩)O,记得好评和采纳,互相帮助

原方程:4.8x+10.7x=4.96右边两项合并同类项:15.5x=4.96左右同除15.5:x=4.96/15.5=0.32

4.8x+10.7x-1.1=6.0615.5x=6.06+1.1x=7.16÷15.5x≈0.4619最后结果保留四位小数

4.8x+10.7x=31解:(4.8+10.7)x=3115.5x=31x=31÷15.5x=2

4.8x+17.6x=4.96解 22.4x=4.96 22.4x/22.4=4.96/22.4 x=0.2

4.8x-0.8x+ 12=324x=32-12x=20/4=5一元一次方程移项除系数

两边同减10.7得X=10.3
