也有现成的:
3x(-9)+7x(-9)

(-54)x1/6x(-1/3)x/3 -5 = (5-x)/2

2(x+1) /3=5(x+1) /6 -1

(1/5)x +1 =(2x+1)/4

(5-2)/2 - (4+x)/3 =1

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

(x-2)/2 - (3x-2)/4 =-1

(5y+1)+(1-y)=(9y+1)+(1-3y)

7(2x-1)-3(4x-1)=4(3x+2)-1

10x=11 x=-1.1

2x+5=45

2(x+8)=48

88-25x=45+6x

566+48x=56-x

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

3x^2+27=0

3x^2-4x-4=0.

(2y+1)^2+3(2y+1)+2=0.

(x-2)^2-3=0

2x^2-5x+1=0

x(8+x)=16

(2x-3)^2-2(2x-3)-3=0

x^2-17x+66=0

(x+1)^2-2(x-1)^2=6x-5 4

(x+2)^2=9(2x-1)^2

回答2:

2[(x+3)-2(x+Ⅰ)]-5=O
7(2x-Ⅰ)-3(4x-Ⅰ)+2(3x-2)+Ⅰ=O
3(x-1)-12=2(2x+3)+4(x+3)
0.8-0.1=0.5x-0.7

回答3:

6X(9一x)=4(3x一7)
