6x%4x=26(解方程)

解:2x=26x=26÷2x=13

6x-4x=26 2x=26 x=24

6x-4x=262x=26x=13

6x一4x=26(6-4)x=262x=26x=26÷2x=13

(1)6x-4x=26, 2x=26, 2x÷2=26÷2, x=13;(2)10.4x-5.4x=75, 5x=75,5x÷5=75÷5, x=15;(3)18m+4m=88, 22m=88, 22m÷22=88÷22,m=4;(4)4y+y=17, 5y=17, 5y÷5=17÷5, y=3.4;(5)9a-6a=12.6, 3a=12.6, 3a÷3=12.6÷3, a=4.2;(6)y-0.36y=64, 0.64y=64,0.64y÷0.64=64÷0.64, x=100.

6x-4x=262x=26x=1310.4x-5.4x=759x=75x=25/3

6X-4X=26解:2X=26X=26÷2X=1310.4X-5.4X=75解:5X=75X=75÷5X=15

6x-4x=20.22x=20.2 x=20.2÷2 x=10.1 有不明白的可以追问!谢谢!!祝学习进步

2x=20.2x=10.1
