一元一次方程计算题（含答案）要90道

Answer 1

0.4(x-0.2)+1.5=0.7x-0.38

x=6

30x-10(10-x)=100

x=5

4(x+2)=5(x-2)

x=18

120-4(x+5)=25

x=18.75

15x+863-65x=54

x=16.18

3(x-2)+1=x-(2x-1)

x=3/2

11x+64-2x=100-9x

x=2

14.59+x-25.31=0

x=10.72

x-48.32+78.51=80

x=49.81

820-16x=45.5×8

x=28.5

(x-6)×7=2x

x=8.4

3x+x=18

X=4.5

0.8x+2.2=6.6

x= 11

12.5-3x=6.5

x=2

1.2(x-0.64)=0.54

x=1.09

x+12.5=3.5x

x=5

8x-22.8=1.2

x=3
