Answer 2

x=38/3(1) 3X-(1/2+1/4)=7/12
3X=7/12+3/4
3X=4/3
X=4/9

(2) 6.6-5X=3/4-4X
6.6-0.75=-4X+5X
X=5.85

(3) 1.1X+2.2=5.5-3.3X
1.1X+3.3X=5.5-2.2
4.4X=3.3
X=3/4=4/3

（4)3x-3=1
x=4/3
(5)5x-3x=4
x=2
(6)3x+7=28
x=7
(7)3x-7=26
x=11
(8)9x-x=16
x=2

(9)24x+x=50
x=2
(10)3x-8=30

Answer 3

0.5x-0.7=6.5-1.3x

Answer 4

2(x-2)-3(4x-1)=9(1-x)
11x+64-2x=100-9x
15-(8-5x)=7x+(4-3x)
3(x-7)-2[9-4(2-x)]=22
3/2[2/3(1/4x-1)-2]-x=2
2(x-2)+2=x+1
5x^2+3x+1=0
7x^2+x+12=0
2x^2+4x+4=0
8x^2+3x+1=0
5x^2+3x+2=0
45x^2+3x+100=0
89x^2+335x+1=0
x+1=3
2x+3=5
3x+5=8
4x+8=12
5x-6=9
2x-x=1
x+3=0
5x+3x=8
3x+1=2x
x-7=6x+2
5x+1=9

Answer 5

2分之1x-6分之9X-2-2=0
