解方程,2.4x—x=2.4怎么写?
答
(2.4-1)X=2.4 1.4X=2.4
答
1.2x=4.8
答
(2.4-1)x=2.4
1.4x=2.4
x=2.4/1.4
=12/7
答
2.4x-x=2.4
1.4x=24
14x=24
7x=12
x=12/7
答
2.4x-x=2.4
x-x=2.4-2.4
x=0
答
2.4x-x=1.4x=2.4
解得:x=12/7
答
2.4x—x=2.4
1.4x=2.4
1.4x÷1.4=2.4÷1.4
x=7分之12
答
1.4x=2.4
14x=24
x=12/7
答
2.4x-x=2.4
(2.4-1)x=2.4
1.4x=2.4
x=2.4/1.4=12/7
