Question

x-+2.6+4点5=8？

Answer 1

×-2.6+4.5=8
×=8-4.5+2.6
×=6.1

Answer 2

8x-1.4=6又 3/5 x+2.6+3.8=3又1/8 2-4x=1/2 [3/11+1/2]-x-2/11=1/4 要过程 8x-1.4=6又 3/5

8x-1.4=6+3/5

8x-1.4=6.6

8x=6.6+1.4=8

x=1

x+2.6+3.8=3又1/8

x+2.6+3.8=3+0.125

x=3+0.125-2.6-3.8

x=-3.275

2-4x=1/2

4x=2-1/2=1.5

x=0.375

[3/11+1/2]-x-2/11=1/4

6/22+11/22-x-4/22=1/4

x=6/22+11/22-4/22-1/4

x=13/22-1/4

x=26/44-11/44

x=15/44

Answer 3

8x-1.4=6又 3/5 x+2.6+3.8=3又1/8 2-4x=1/2 [3/11+1/2]-x-2/11=1/4 要过程 8x-1.4=6又 3/5

8x-1.4=6+3/5

8x-1.4=6.6

8x=6.6+1.4=8

x=1

x+2.6+3.8=3又1/8

x+2.6+3.8=3+0.125

x=3+0.125-2.6-3.8

x=-3.275

2-4x=1/2

4x=2-1/2=1.5

x=0.375

[3/11+1/2]-x-2/11=1/4

6/22+11/22-x-4/22=1/4

x=6/22+11/22-4/22-1/4

x=13/22-1/4

x=26/44-11/44

x=15/44
