别忘了列算式

Answer 1

2(0.9-x)+4=4.3
1.8-2x+4=4.3
5.8-2x=4.3
2x=5.8-4.3
2x=1.5
x=0.75

(x+1.8)/8=6.6.
x+1.8=52.8
x=52.8-1.8
x=51

12x+12=16x.
16x-12x=12
4x=12
x=3

12x-35=5x.
12x-5x=35
7x=35
x=5

X/0.5-10+2=0
0.5*x/0.5-10*0.5+2*0.5=0
x-5+1=0
x-4=0
x=4

3*1.8-0.6x=5.1
5.4-0.6x=5.1
0.6x=5.4-5.1
0.6x=0.3
x=0.5

6.85*4+6x=32.2
27.4+6x=32.3
6x=32.2-27.4
6x=4.8
x=0.8

Answer 2

X=0.75
X=51
X=3
X=5
X=4
X=0.5
X=0.8

Answer 3

求X么？

追问

是，请快告诉我可以吗，我很急
